Returns column information for a single stored procedure or user-defined function in the current environment.

-- Azure SQL Data Warehouse and Parallel Data Warehouse sp_sproc_columns [[@procedure_name = ] 'name'] [ , [@procedure_owner = ] 'owner'] [ , [@procedure_qualifier = ] 'qualifier'] [ , [@column_name = ] 'column_name'] [ , [@ODBCVer = ] 'ODBCVer'] [ , [@fUsePattern = ] 'fUsePattern']
[ @procedure_name = ] 'name'
Is the name of the procedure used to return catalog information. name is nvarchar(390), with a default of %, which means all tables in the current database. Wildcard pattern matching is supported.
[ @procedure_owner =] 'owner'
Is the name of the owner of the procedure. owneris nvarchar(384), with a default of NULL. Wildcard pattern matching is supported. If owner is not specified, the default procedure visibility rules of the underlying DBMS apply.
If the current user owns a procedure with the specified name, information about that procedure is returned. If owneris not specified and the current user does not own a procedure with the specified name, sp_sproc_columns looks for a procedure with the specified name that is owned by the database owner. If the procedure exists, information about its columns is returned.
[ @procedure_qualifier =] 'qualifier'
Is the name of the procedure qualifier. qualifier is sysname, with a default of NULL. Various DBMS products support three-part naming for tables (qualifier.owner.name). In SQL Server, this parameter represents the database name. In some products, it represents the server name of the table's database environment.
[ @column_name =] 'column_name'
Is a single column and is used when only one column of catalog information is desired. column_name is nvarchar(384), with a default of NULL. If column_name is omitted, all columns are returned. Wildcard pattern matching is supported. For maximum interoperability, the gateway client should assume only ISO standard pattern matching (the % and _ wildcard characters).
[ @ODBCVer =] 'ODBCVer'
Is the version of ODBC being used. ODBCVer is int, with a default of 2, which indicates ODBC version 2.0. For more information about the difference between ODBC version 2.0 and ODBC version 3.0, refer to the ODBC SQLProcedureColumns specification for ODBC version 3.0
[ @fUsePattern =] 'fUsePattern'
Determines whether the underscore (_), percent (%), and bracket ([ ]) characters are interpreted as wildcard characters. Valid values are 0 (pattern matching is off) and 1 (pattern matching is on). fUsePattern is bit, with a default of 1.
|Column name||Data type||Description|
|PROCEDURE_QUALIFIER||sysname||Procedure qualifier name. This column can be NULL.|
|PROCEDURE_OWNER||sysname||Procedure owner name. This column always returns a value.|
|PROCEDURE_NAME||nvarchar(134)||Procedure name. This column always returns a value.|
|COLUMN_NAME||sysname||Column name for each column of the TABLE_NAME returned. This column always returns a value.|
|COLUMN_TYPE||smallint||This field always returns a value:|
0 = SQL_PARAM_TYPE_UNKNOWN
1 = SQL_PARAM_TYPE_INPUT
2 = SQL_PARAM_TYPE_OUTPUT
3 = SQL_RESULT_COL
4 = SQL_PARAM_OUTPUT
5 = SQL_RETURN_VALUE
|DATA_TYPE||smallint||Integer code for an ODBC data type. If this data type cannot be mapped to an ISO type, the value is NULL. The native data type name is returned in the TYPE_NAME column.|
|TYPE_NAME||sysname||String representation of the data type. This is the data type name as presented by the underlying DBMS.|
|PRECISION||int||Number of significant digits. The return value for the PRECISION column is in base 10.|
|LENGTH||int||Transfer size of the data.|
|SCALE||smallint||Number of digits to the right of the decimal point.|
|RADIX||smallint||Is the base for numeric types.|
1 = Data type can be created allowing null values.
0 = Null values are not allowed.
|REMARKS||varchar(254)||Description of the procedure column. SQL Server does not return a value for this column.|
|COLUMN_DEF||nvarchar(4000)||Default value of the column.|
|SQL_DATA_TYPE||smallint||Value of the SQL data type as it appears in the TYPE field of the descriptor. This column is the same as the DATA_TYPE column, except for the datetime and ISO interval data types. This column always returns a value.|
|SQL_DATETIME_SUB||smallint||The datetime ISO interval subcode if the value of SQL_DATA_TYPE is SQL_DATETIME or SQL_INTERVAL. For data types other than datetime and ISO interval, this field is NULL.|
|CHAR_OCTET_LENGTH||int||Maximum length in bytes of a character or binary data type column. For all other data types, this column returns a NULL.|
|ORDINAL_POSITION||int||Ordinal position of the column in the table. The first column in the table is 1. This column always returns a value.|
|IS_NULLABLE||varchar(254)||Nullability of the column in the table. ISO rules are followed to determine nullability. An ISO compliant DBMS cannot return an empty string.|
Displays YES if the column can include NULLS and NO if the column cannot include NULLS.
This column returns a zero-length string if nullability is unknown.
The value returned for this column is different from the value returned for the NULLABLE column.
|SS_DATA_TYPE||tinyint||SQL Server data type used by extended stored procedures. For more information, see Data Types (Transact-SQL).|
sp_sproc_columns is equivalent to SQLProcedureColumns in ODBC. The results returned are ordered by PROCEDURE_QUALIFIER, PROCEDURE_OWNER, PROCEDURE_NAME, and the order that the parameters appear in the procedure definition.
Requires SELECT permission on the schema.
