Question

I have a column named Sysdate in several tables, which is causing SQL errors when I try to Select it. It works if “Sysdate” is enclosed in double-quotes, e.g.

SELECT "Sysdate" FROM table1

When I try to use aliases it causes syntax errors:

SELECT t1."Sysdate" FROM table1 AS t1

Please advise.

Thank you,

Max.

For what database? MySQL allows you to escape reserved keywords using backticks:

SELECT `sysdate` FROM TABLE1

In SQL Server, you use hard brackets:

SELECT [sysdate] FROM TABLE1

Oracle uses double quotes:

SELECT "sysdate" FROM TABLE1
