Vuln Sigs for SQL Injection

There are several sigs described as "HTTP SQL Injection" (30514, 33338, 33340, 33305, and maybe others) that are server-side mediums with a default alert. What are these signatures looking for? Atypical SQL statements that indicate an attempt to get more from a database than one might normally need? More info in the description would be helpful.

We were looking couple of patterns:

1) some SQL sentences/keywords which were used for SQL Injection attempt.

   like "union select", "select char" something.

2) Some SQL functions which were used for SQL injection evasion.

3) Some SQL "or" conditions which were used for SQL injection probe, like "or 1=1".

If customer found those alerts, it might be a probe or from a scanner. It does not means customer's

server is vulnerable.
