                                   boolean isValidMetaData)

Method Detail

getResultSetMetaData

public SFResultSetMetaData getResultSetMetaData()

setResultSetMetaData

public void setResultSetMetaData(SFResultSetMetaData resultSetMetaData)

getNumberOfBinds

public int getNumberOfBinds()

getMetaDataForBindParam

public MetaDataOfBinds getMetaDataForBindParam(int param)
                                        throws SQLException

Throws:

SQLException

setNumberOfBinds

public void setNumberOfBinds(int numberOfBinds)

isValidMetaData

public boolean isValidMetaData()

Is a valid metadata or not. If true, this object is a valid metadata from describe. If false, a dummy/empty metadata generated because prepare statement fails.

This is used to determine if the content is valid or not, e.g., number of bind parameters.

Returns:

true or false

isArrayBindSupported

public boolean isArrayBindSupported()

According to StatementType, to decide whether array binds supported or not

Currently, only INSERT supports array bind

Returns:

true if array binds is supported.

getStatementType

public SFStatementType getStatementType()

emptyMetaData

public static SFPreparedStatementMetaData emptyMetaData()

Generates an empty/invalid metadata for placeholder.

Returns:

statement metadata
