Entering Parameter Values

If a parameter value for a system procedure contains punctuation or embedded blanks, or is a reserved word, you must enclose it in single or double quotes. If the parameter is an object name qualified by a database name or owner name, enclose the entire name in single or double quotes.

Note: Do not use delimited identifiers as system procedure parameters; they may produce unexpected results.
If a procedure has multiple optional parameters, you can supply parameters in the following form instead of supplying all the parameters:
@parametername = value

You can also use “null” as a placeholder for a parameter. Do not enclose “null” in quotes.

SQL has no rules about the number of words you can put on a line or where you must break a line. If you issue a system procedure followed by a command, the SAP ASE server attempts to execute the system procedure, then the command. For example, if you execute the following command, the SAP ASE server returns the output from sp_help, then runs the checkpoint command:
sp_help checkpoint

If you specify more parameters than the number of parameters expected by the system procedure, the extra parameters are ignored by the SAP ASE server.
