  - DECIMAL
```
public static final MysqlType DECIMAL
```
    DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL] A packed "exact" fixed-point number. M is the total number of digits (the precision) and D is the number of digits after the decimal point (the scale). The decimal point and (for negative numbers) the "-" sign are not counted in M. If D is 0, values have no decimal point or fractional part. The maximum number of digits (M) for DECIMAL is 65. The maximum number of supported decimals (D) is 30. If D is omitted, the default is 0. If M is omitted, the default is 10. Protocol: FIELD_TYPE_DECIMAL = 0 Protocol: FIELD_TYPE_NEWDECIMAL = 246 These types are synonyms for DECIMAL: DEC[(M[,D])] [UNSIGNED] [ZEROFILL], NUMERIC[(M[,D])] [UNSIGNED] [ZEROFILL], FIXED[(M[,D])] [UNSIGNED] [ZEROFILL]

  - BOOLEAN
```
public static final MysqlType BOOLEAN
```
    BOOL, BOOLEAN These types are synonyms for TINYINT(1). A value of zero is considered false. Nonzero values are considered true BOOLEAN is converted to TINYINT(1) during DDL execution i.e. it has the same precision=3. Thus we have to look at full data type name and convert TINYINT to BOOLEAN (or BIT) if it has "(1)" length specification. Protocol: FIELD_TYPE_TINY = 1
  - SMALLINT
```
public static final MysqlType SMALLINT
```
    SMALLINT[(M)] [UNSIGNED] [ZEROFILL] A small integer. The signed range is -32768 to 32767. The unsigned range is 0 to 65535. Protocol: FIELD_TYPE_SHORT = 2

  - FLOAT
```
public static final MysqlType FLOAT
```
    FLOAT[(M,D)] [UNSIGNED] [ZEROFILL] A small (single-precision) floating-point number. Permissible values are -3.402823466E+38 to -1.175494351E-38, 0, and 1.175494351E-38 to 3.402823466E+38. These are the theoretical limits, based on the IEEE standard. The actual range might be slightly smaller depending on your hardware or operating system. M is the total number of digits and D is the number of digits following the decimal point. If M and D are omitted, values are stored to the limits permitted by the hardware. A single-precision floating-point number is accurate to approximately 7 decimal places. Protocol: FIELD_TYPE_FLOAT = 4 Additionally: FLOAT(p) [UNSIGNED] [ZEROFILL] A floating-point number. p represents the precision in bits, but MySQL uses this value only to determine whether to use FLOAT or DOUBLE for the resulting data type. If p is from 0 to 24, the data type becomes FLOAT with no M or D values. If p is from 25 to 53, the data type becomes DOUBLE with no M or D values. The range of the resulting column is the same as for the single-precision FLOAT or double-precision DOUBLE data types.

    DOUBLE[(M,D)] [UNSIGNED] [ZEROFILL] A normal-size (double-precision) floating-point number. Permissible values are -1.7976931348623157E+308 to -2.2250738585072014E-308, 0, and 2.2250738585072014E-308 to 1.7976931348623157E+308. These are the theoretical limits, based on the IEEE standard. The actual range might be slightly smaller depending on your hardware or operating system. M is the total number of digits and D is the number of digits following the decimal point. If M and D are omitted, values are stored to the limits permitted by the hardware. A double-precision floating-point number is accurate to approximately 15 decimal places. Protocol: FIELD_TYPE_DOUBLE = 5 These types are synonyms for DOUBLE: DOUBLE PRECISION[(M,D)] [UNSIGNED] [ZEROFILL], REAL[(M,D)] [UNSIGNED] [ZEROFILL]. Exception: If the REAL_AS_FLOAT SQL mode is enabled, REAL is a synonym for FLOAT rather than DOUBLE.

  - TIMESTAMP
```
public static final MysqlType TIMESTAMP
```

TIMESTAMP values are stored as the number of seconds since the epoch ('1970-01-01 00:00:00' UTC). A TIMESTAMP cannot represent the value '1970-01-01 00:00:00' because that is equivalent to 0 seconds from the epoch and the value 0 is reserved for representing '0000-00-00 00:00:00', the "zero" TIMESTAMP value. An optional fsp value in the range from 0 to 6 may be given to specify fractional seconds precision. A value of 0 signifies that there is no fractional part. If omitted, the default precision is 0. Protocol: FIELD_TYPE_TIMESTAMP = 7
  - BIGINT
```
public static final MysqlType BIGINT
```
    BIGINT[(M)] [UNSIGNED] [ZEROFILL] A large integer. The signed range is -9223372036854775808 to 9223372036854775807. The unsigned range is 0 to 18446744073709551615. Protocol: FIELD_TYPE_LONGLONG = 8 SERIAL is an alias for BIGINT UNSIGNED NOT NULL AUTO_INCREMENT UNIQUE.

  - DATE
```
public static final MysqlType DATE
```
    DATE A date. The supported range is '1000-01-01' to '9999-12-31'. MySQL displays DATE values in 'YYYY-MM-DD' format, but permits assignment of values to DATE columns using either strings or numbers. Protocol: FIELD_TYPE_DATE = 10
  - TIME
```
public static final MysqlType TIME
```
    TIME[(fsp)] A time. The range is '-838:59:59.000000' to '838:59:59.000000'. MySQL displays TIME values in 'HH:MM:SS[.fraction]' format, but permits assignment of values to TIME columns using either strings or numbers. An optional fsp value in the range from 0 to 6 may be given to specify fractional seconds precision. A value of 0 signifies that there is no fractional part. If omitted, the default precision is 0. Protocol: FIELD_TYPE_TIME = 11
  - DATETIME

MySQL displays DATETIME values in 'YYYY-MM-DD HH:MM:SS[.fraction]' format, but permits assignment of values to DATETIME columns using either strings or numbers. An optional fsp value in the range from 0 to 6 may be given to specify fractional seconds precision. A value of 0 signifies that there is no fractional part. If omitted, the default precision is 0. Protocol: FIELD_TYPE_DATETIME = 12
  - YEAR
```
public static final MysqlType YEAR
```
    YEAR[(4)] A year in four-digit format. MySQL displays YEAR values in YYYY format, but permits assignment of values to YEAR columns using either strings or numbers. Values display as 1901 to 2155, and 0000. Protocol: FIELD_TYPE_YEAR = 13
  - VARCHAR
```
public static final MysqlType VARCHAR
```
    [NATIONAL] VARCHAR(M) [CHARACTER SET charset_name] [COLLATE collation_name] A variable-length string. M represents the maximum column length in characters. The range of M is 0 to 65,535. The effective maximum length of a VARCHAR is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used. For example, utf8 characters can require up to three bytes per character, so a VARCHAR column that uses the utf8 character set can be declared to be a maximum of 21,844 characters. MySQL stores VARCHAR values as a 1-byte or 2-byte length prefix plus data. The length prefix indicates the number of bytes in the value. A VARCHAR column uses one length byte if values require no more than 255 bytes, two length bytes if values may require more than 255 bytes. Note MySQL 5.7 follows the standard SQL specification, and does not remove trailing spaces from VARCHAR values. VARCHAR is shorthand for CHARACTER VARYING. NATIONAL VARCHAR is the standard SQL way to define that a VARCHAR column should use some predefined character set. MySQL 4.1 and up uses utf8 as this predefined character set. NVARCHAR is shorthand for NATIONAL VARCHAR. Protocol: FIELD_TYPE_VARCHAR = 15 Protocol: FIELD_TYPE_VAR_STRING = 253
  - VARBINARY
```
public static final MysqlType VARBINARY
```
    VARBINARY(M) The VARBINARY type is similar to the VARCHAR type, but stores binary byte strings rather than nonbinary character strings. M represents the maximum column length in bytes. Protocol: FIELD_TYPE_VARCHAR = 15 Protocol: FIELD_TYPE_VAR_STRING = 253
  - BIT
```
public static final MysqlType BIT
```
    BIT[(M)] A bit-field type. M indicates the number of bits per value, from 1 to 64. The default is 1 if M is omitted. Protocol: FIELD_TYPE_BIT = 16
  - JSON
```
public static final MysqlType JSON
```
    The size of JSON documents stored in JSON columns is limited to the value of the max_allowed_packet system variable (max value 1073741824). (While the server manipulates a JSON value internally in memory, it can be larger; the limit applies when the server stores it.) Protocol: FIELD_TYPE_BIT = 245
  - ENUM
```
public static final MysqlType ENUM
```
    ENUM('value1','value2',...) [CHARACTER SET charset_name] [COLLATE collation_name] An enumeration. A string object that can have only one value, chosen from the list of values 'value1', 'value2', ..., NULL or the special '' error value. ENUM values are represented internally as integers. An ENUM column can have a maximum of 65,535 distinct elements. (The practical limit is less than 3000.) A table can have no more than 255 unique element list definitions among its ENUM and SET columns considered as a group Protocol: FIELD_TYPE_ENUM = 247
  - SET
```
public static final MysqlType SET
```
    SET('value1','value2',...) [CHARACTER SET charset_name] [COLLATE collation_name] A set. A string object that can have zero or more values, each of which must be chosen from the list of values 'value1', 'value2', ... SET values are represented internally as integers. A SET column can have a maximum of 64 distinct members. A table can have no more than 255 unique element list definitions among its ENUM and SET columns considered as a group Protocol: FIELD_TYPE_SET = 248
  - TINYBLOB
```
public static final MysqlType TINYBLOB
```
    TINYBLOB A BLOB column with a maximum length of 255 (28 - 1) bytes. Each TINYBLOB value is stored using a 1-byte length prefix that indicates the number of bytes in the value. Protocol:FIELD_TYPE_TINY_BLOB = 249
  - TINYTEXT
```
public static final MysqlType TINYTEXT
```
    TINYTEXT [CHARACTER SET charset_name] [COLLATE collation_name] A TEXT column with a maximum length of 255 (28 - 1) characters. The effective maximum length is less if the value contains multibyte characters. Each TINYTEXT value is stored using a 1-byte length prefix that indicates the number of bytes in the value. Protocol:FIELD_TYPE_TINY_BLOB = 249
  - MEDIUMBLOB
```
public static final MysqlType MEDIUMBLOB
```
    MEDIUMBLOB A BLOB column with a maximum length of 16,777,215 (224 - 1) bytes. Each MEDIUMBLOB value is stored using a 3-byte length prefix that indicates the number of bytes in the value. Protocol: FIELD_TYPE_MEDIUM_BLOB = 250
  - MEDIUMTEXT
```
public static final MysqlType MEDIUMTEXT
```
    MEDIUMTEXT [CHARACTER SET charset_name] [COLLATE collation_name] A TEXT column with a maximum length of 16,777,215 (224 - 1) characters.

Protocol: FIELD_TYPE_MEDIUM_BLOB = 250
  - LONGBLOB
```
public static final MysqlType LONGBLOB
```
    LONGBLOB A BLOB column with a maximum length of 4,294,967,295 or 4GB (232 - 1) bytes. The effective maximum length of LONGBLOB columns depends on the configured maximum packet size in the client/server protocol and available memory. Each LONGBLOB value is stored using a 4-byte length prefix that indicates the number of bytes in the value. Protocol: FIELD_TYPE_LONG_BLOB = 251
  - LONGTEXT
```
public static final MysqlType LONGTEXT
```
    LONGTEXT [CHARACTER SET charset_name] [COLLATE collation_name] A TEXT column with a maximum length of 4,294,967,295 or 4GB (232 - 1) characters. The effective maximum length is less if the value contains multibyte characters. The effective maximum length of LONGTEXT columns also depends on the configured maximum packet size in the client/server protocol and available memory. Each LONGTEXT value is stored using a 4-byte length prefix that indicates the number of bytes in the value. Protocol: FIELD_TYPE_LONG_BLOB = 251
  - BLOB
```
public static final MysqlType BLOB
```
    BLOB[(M)] A BLOB column with a maximum length of 65,535 (216 - 1) bytes. Each BLOB value is stored using a 2-byte length prefix that indicates the number of bytes in the value. An optional length M can be given for this type. If this is done, MySQL creates the column as the smallest BLOB type large enough to hold values M bytes long. Protocol: FIELD_TYPE_BLOB = 252
  - TEXT
```
public static final MysqlType TEXT
```
    TEXT[(M)] [CHARACTER SET charset_name] [COLLATE collation_name] A TEXT column with a maximum length of 65,535 (216 - 1) characters. The effective maximum length is less if the value contains multibyte characters. Each TEXT value is stored using a 2-byte length prefix that indicates the number of bytes in the value. An optional length M can be given for this type. If this is done, MySQL creates the column as the smallest TEXT type large enough to hold values M characters long. Protocol: FIELD_TYPE_BLOB = 252
  - CHAR
```
public static final MysqlType CHAR
```
    [NATIONAL] CHAR[(M)] [CHARACTER SET charset_name] [COLLATE collation_name] A fixed-length string that is always right-padded with spaces to the specified length when stored. M represents the column length in characters. The range of M is 0 to 255. If M is omitted, the length is 1. Note Trailing spaces are removed when CHAR values are retrieved unless the PAD_CHAR_TO_FULL_LENGTH SQL mode is enabled. CHAR is shorthand for CHARACTER. NATIONAL CHAR (or its equivalent short form, NCHAR) is the standard SQL way to define that a CHAR column should use some predefined character set. MySQL 4.1 and up uses utf8 as this predefined character set. MySQL permits you to create a column of type CHAR(0). This is useful primarily when you have to be compliant with old applications that depend on the existence of a column but that do not actually use its value. CHAR(0) is also quite nice when you need a column that can take only two values: A column that is defined as CHAR(0) NULL occupies only one bit and can take only the values NULL and '' (the empty string). Protocol: FIELD_TYPE_STRING = 254
  - BINARY
```
public static final MysqlType BINARY
```
    BINARY(M) The BINARY type is similar to the CHAR type, but stores binary byte strings rather than nonbinary character strings. M represents the column length in bytes. The CHAR BYTE data type is an alias for the BINARY data type. Protocol: no concrete type on the wire TODO: really?
  - GEOMETRY

public static MysqlType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (MysqlType c : MysqlType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static MysqlType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null

    true if the MySQL Type is a Decimal/Number Type
  - getPrecision
```
public Long getPrecision()
```
    The PRECISION column represents the maximum column size that the server supports for the given datatype.
    - For numeric data, this is the maximum precision.
    - For character data, this is the length in characters.
    - For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component).
    - For binary data, this is the length in bytes.
    - For the ROWID datatype, this is the length in bytes.
    - Null is returned for data types where the column size is not applicable.
    Returns:
    
    precision
