Method Detail

getJavaType

int getJavaType(int sqlType,
                int columnSize,
                int decimalDigits)

Gets the JAVA type of the given SQL type.

Parameters:

sqlType - The SQL type ID from java.sql.Types.

columnSize - The size of the SQL type.

decimalDigits - The number of decimal digits.

Returns:

The SQL type name.

getJavaTypeName

String getJavaTypeName(int sqlType,
                       int columnSize,
                       int decimalDigits,
                       boolean allowPrimitive,
                       boolean fullyQualified)

Gets the name of the given SQL type

Parameters:

sqlType - The SQL type ID from java.sql.Types.

columnSize - The size of the SQL type.

decimalDigits - The number of decimal digits.

allowPrimitive - If true, uses the simple types (int, long, float, double, ...) for numeric values, otherwise returns the wrapper classed for these types.

fullyQualified - If true, returns the fully qualified class names for system classes, else returns the system class names without java.lang package prefix.

Returns:

The JAVA type name.

getSqlTypeName

String getSqlTypeName(int sqlType)

Gets the name of the given SQL type

Parameters:

sqlType - The SQL type ID from java.sql.Types.
