Default ":" character problem in sqls

When I use : character in TAdo's SQL.Text;
ExecSql method return this error:
"Parameter object is improperly defined. inconsistent or incomplete information was provided"

AdoQuery1.Sql.Text :=
'--Author: Dolphin ' + //there is a problem in this line because of ":" character

How can I use ":" characters in TAdoQuery's. (they'are not parameter only sql text)
Best Regards...

Default RE: ":" character problem in sqls

Anytime you use a ":" in SQL text such as

SQLQuery1.SQL.Add('Select * from MyTable Where MyField =:MyParam

Delphi expects you to have created a parameter that is a variable that can be changed for input or output. Look at a query.params or ADOQuery.parmaeters.

I know of no way to use a colon in SQL syntax and SQL syntax doesn't use colons unless you are prefixing host variable names, i.e. the paramater. if Dolphin is a parmeter or a host variable then the colon must be immediately before the name i.e. AUTHOR OLPHIN not

Hope I may have helped a bit.

Hi, John
Thanks for your answer.
The line which include ":" charecter is a only comment line, not a parameter you know.
When I create sql stored procs I usualy use ":" charecter in comment lines or messages.
But I can't use in TAdo.query.sql
