Problem Note 33744: An incorrect buffer break occurs when calling a macro from an EXECUTE statement that specifies a parameter with an "at" sign (@) in the parameter name
 |  |  |  |  |
An incorrect buffer break occurs in the following situations:
- You call a macro from an EXECUTE statement that calls an SQL Server 2005 stored procedure.
- The stored procedure contains many parameters with @ in the parameter names (in the form @parameter-name).
This naming convention can cause the macro to be parsed with a break between @ and the parameter name, resulting in an error.
The following code is an example of code that can produce the error:
proc sql;
connect to odbc as mydb (noprompt="dsn=mydsn;");
execute (sys.sp_addextendedproperty
@name = N'Caption',
@value = N%str(%')&vlab.%str(%'),
@level0type = N'SCHEMA',
@level0name = N'dbo',
@level1type = N'TABLE',
@level1name = N%str(%')encounter_fy&fy._&ds.%str(%'),
@level2type = N'COLUMN',
@level2name = N%str(%')&vname.%str(%')
)
by mydb
;
quit;
The error that is generated is as follows:
ERROR: CLI execute error: [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare the scalar variable "@"
