Hello, I\'m new to SQL and have run across a problem. First of all, here is the complete SQL code that results in an error:

SELECT WC_First_Name, WC_Last_Name, WC_SSN, WC_Availability_Type      	FROM Worker_Client      WHERE WC_City = \'Sacramento\'      	AND      WC_State = \'CA\'      	AND      WC_HS_Status = 1      	AND      WC_College_Status = 2      	AND      WC_SSN IN(SELECT WC_SSN FROM WC_Skill Where Skill_ID IN(\'1166\',\'1198\',\'1180\'))        	AND      WC_SSN IN(SELECT WC_SSN FROM WC_Certificate Where Certificate_ID IN(\'1001\',\'1003\',\'1007\',\'1008\'))

When I run this code, I get this error:

MySQL said:

You have an error in your SQL syntax near \'SELECT WC_SSN
IN ( \'1166\', \'1198\', \'1180\' ) ) AN\' at line 5

The weird thing is that this code works fine when I exchange the insides of the two IN Statements with a test number like \'1004\'. For example, this code works:

SELECT WC_First_Name, WC_Last_Name, WC_SSN, WC_Availability_TypeFROM Worker_ClientWHERE WC_City = \'Sacramento\' AND WC_State = \'CA\' AND WC_HS_Status = 1 AND WC_College_Status = 2 AND WC_SSNIN (\'1004\') AND WC_SSNIN (\'1004\')

Another weird thing is that the code that I just took out in the previous example runs fine on its own. For example, these two pieces of code (from inside the IN Statements) works just fine by themselves:

SELECT WC_SSNFROM WC_SkillWHERE Skill_IDIN (\'1166\', \'1198\', \'1180\')

SELECT WC_SSNFROM WC_CertificateWHERE Certificate_IDIN (\'1001\', \'1003\', \'1007\', \'1008\')

I am using PHP 4.1.2 and MySQL 3.23.39

Thanks in advance. : )

You need version 4.1 of MySql to be able to use subqueries.
If you are still using mysql_ functions, STOP! Use mysqli_ or PDO. The longer you leave it the more you will have to rewrite.
