type - A constant of Types

Returns:

A string corresponding to the JAVA SQL type constant.

stringToType

public static int stringToType(java.lang.String s)

Parameters:

s - A String representing the JAVA SQL type.

Returns:

The JAVA SQL type constant.If the string is unknown, return Types.OTHER.

isNumeric

public static boolean isNumeric(int type)

Parameters:

type - An JDBC type contant.

Returns:

Whether this type is numeric, i.e. values of this type do not need to be quoted.

isString

deferrabilityStringToShort

public static short deferrabilityStringToShort(java.lang.String s)

Parse deferrability string of the deferrability attribute of a foreignkey tag.

Parameters:

s - "NotDeferrable", "InitiallyDeferred" or "InitiallyImmediate".

Returns:

DatabaseMetaData.importedKeyNotDeferrable, DatabaseMetaData.importedKeyInitiallyDeferred or DatabaseMetaData.importedKeyInitiallyImmediate. If s is null or an unrecognized string, the default value DatabaseMetaData.importedKeyNotDeferrable is assumed.
