COLUMN_TYPE

An integer value representing the type of the parameter:

Return value	Parameter type

2 (SQL_PARAM_INPUT_OUTPUT)	Input/output (INOUT) parameter.
3 (SQL_PARAM_OUTPUT)	Output (OUT) parameter.

DATA_TYPE The SQL data type for the parameter represented as an integer value.

TYPE_NAME A string representing the data type for the parameter.

COLUMN_SIZE An integer value representing the size of the parameter.

BUFFER_LENGTH Maximum number of bytes necessary to store data for this parameter.

DECIMAL_DIGITS The scale of the parameter, or NULL where scale is not applicable.

NUM_PREC_RADIX An integer value of either 10 (representing an exact numeric data type), 2 (representing an approximate numeric data type), or NULL (representing a data type for which radix is not applicable).

NULLABLE An integer value representing whether the parameter is nullable or not.

REMARKS Description of the parameter.

COLUMN_DEF Default value for the parameter.

SQL_DATA_TYPE An integer value representing the size of the parameter.

SQL_DATETIME_SUB Returns an integer value representing a datetime subtype code, or NULL for SQL data types to which this does not apply.

CHAR_OCTET_LENGTH Maximum length in octets for a character data type parameter, which matches COLUMN_SIZE for single-byte character set data, or NULL for non-character data types.

ORDINAL_POSITION The 1-indexed position of the parameter in the CALL statement.
