if exists update else insert

I want to know if the next piece of code is correct:

 SqlCommand cmd = new SqlCommand(
   "IF NOT EXISTS(SELECT count(*) from Raspunsuri where id_intrebare=2)" +
   "Insert INTO Raspunsuri VALUES(@raspuns,@cnp,@data,2,@ip,@idsesiune)" +
   "else" +
   "UPDATE Raspunsuri SET <a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="83f1e2f0f3f6edf0bec3f1e2f0f3f6edf0">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c9aaa6ad96a7bca4acbba0aa96b9acbbbaa6a7a8a5f489aaa7b9">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="32565346536d40534142475c410f7256534653">[email protected]</a>,id_intrebare=2,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a8c1d8f7dddbcdda95e8c1d8">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="82ebe6ddf1e7f1ebf7ece7bfc2ebe6f1e7f1ebf7ece7">[email protected]</a> WHERE id_intrebare=2", con);

All the parameters are correct that I want to insert but it seems this piece of code doesn’t do the insert or update.Do you have any suggestions?it’s a sql query combined with c#..

Method 1

Inspect the string that’s created by that command: some words need spaces between them.

 SqlCommand cmd = new SqlCommand("IF NOT EXISTS(SELECT 1 from Raspunsuri where id_intrebare=2)" +
                " Insert INTO Raspunsuri VALUES(@raspuns,@cnp,@data,2,@ip,@idsesiune)" +
                " else" +
                " UPDATE Raspunsuri SET <a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7200130102071c014f3200130102071c01">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bcdfd3d8e3d2c9d1d9ced5dfe3ccd9cecfd3d2ddd081fcdfd2cc">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="85e1e4f1e4daf7e4f6f5f0ebf6b8c5e1e4f1e4">[email protected]</a>,id_intrebare=2,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6b021b341e180e19562b021b">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f19895ae82948298849f94ccb1989582948298849f94">[email protected]</a> WHERE id_intrebare=2", con);

Method 2

Description

No because you select count that has always a value.

select a column or * instead.

Sample

SqlCommand cmd = new SqlCommand(
   "IF NOT EXISTS(SELECT id_intrebare from Raspunsuri where id_intrebare=2) " +
   "Insert INTO Raspunsuri VALUES(@raspuns,@cnp,@data,2,@ip,@idsesiune) " +
   "else " +
   "UPDATE Raspunsuri SET <a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="3446554744415a47097446554744415a47">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="81e2eee5deeff4ece4f3e8e2def1e4f3f2eeefe0edbcc1e2eff1">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="dabebbaebb85a8bba9aaafb4a9e79abebbaebb">[email protected]</a>,id_intrebare=2,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1f766f406a6c7a6d225f766f">[email protected]</a>,<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="9cf5f8c3eff9eff5e9f2f9a1dcf5f8eff9eff5e9f2f9">[email protected]</a> WHERE id_intrebare=2", con);

Method 3

Why don’t you use the MERGE command?

Method 4

You can try executing the query in SQL Server Management Studio window first. This will give you an easy way to debug the things

Method 5

I think the blank spaces are missing between the “else” statement
Also ensure that you have provided all the columns in the values part
