Method Detail

definition2param

public static java.lang.String definition2param(java.lang.String sqlTypeDef)

Extracts parameter for type convertor from the SQL type definition of the form "SQL_TYPE_NAME[PARAMETER]". If the type is not parameterized, returns null.

Parameters:

sqlTypeDef - SQL type definition (e.g. char[01]).

Returns:

Parameter (e.g. "01") or null if not parameterized.

definition2type

public static java.lang.String definition2type(java.lang.String sqlTypeDef)

Extracts SQL type name from the the SQL type definition of the form "SQL_TYPE_NAME[PARAMETER]".

Parameters:

sqlTypeDef - SQL type definition (e.g. char[01]).

Returns:

SQL type name (e.g. "char").
