Strange query during a stored-procedure

[former_SQLA_member1694891]

Hi,

I made a stored-procedure that charck if a signature is good and re-do the signature (with different values).

I look with the profiler what appen and the server have execute 11 000+ time a query that isn't in my procedure during the execution of this last one.

Here the query :

select cast(null as char(128)) as "TABLE_CAT",
    "SYSUSER"."user_name" as "TABLE_SCHEM",
    "SYSTABLE"."table_name" as "TABLE_NAME",
    "column_name" as "COLUMN_NAME",
    cast((select "count"() from "SYS"."SYSCOLUMN" as "other" where "table_id" = "SYSTABLE"."table_id" and "column_id" <= "SYSCOLUMN"."column_id" and "pkey" = 'Y') as smallint) as "KEY_SEQ",
    "SYSCONSTRAINT"."constraint_name" as "PK_NAME"
from "SYS"."SYSCOLUMN" join "SYS"."SYSTABLE" on "SYSCOLUMN"."table_id" = "SYSTABLE"."table_id" join "SYS"."SYSUSER" on "SYSTABLE"."creator" = "SYSUSER"."user_id" join "SYS"."SYSCONSTRAINT" on("SYSTABLE"."object_id" = "SYSCONSTRAINT"."table_object_id")
where "user_name" = 'DBA'
and "table_name" = 'SIG'
and "pkey" = 'Y' and "constraint_type" = 'P'
order by 1 asc,2 asc,3 asc,5 asc

I passed the query, to see what is the result, it return this : TABLE_CAT;TABLE_SCHEM;TABLE_NAME;COLUMN_NAME;KEY_SEQ;PK_NAME

Null;'DBA';'SIG';'SigId';1;'ASA209'

This is the primary key of the table where I store the signature.

So did someone knows why the server run it 11 000+ times ?

thanks in advence.

Are you using SQL Anywhere 17?

If so, did you use Comprehensive Profiling or Targeted Profiling?

In Comprehensive Profiling, the Operations and Statements tabs show statements from the client and the Profiling tab shows statements inside stored procedures.

In Targeted Profiling, the Operations and Statements tabs show statements from both the client AND inside stored procedures but it's not clear which is which; the Profiling tab is empty.

IMO the Profiling tab of Comprehensive Profiling is worth the effort... it is wonderful for finding bottlenecks inside stored procedures.

To find runaway connections, I suggest Foxhound.

Each time you run a query that returns a result set in Interactive SQL, the getPrimaryKeys() method will be executed. This is the "select null as "TABLE_CAT",null as "TABLE_SCHEM",..." that you see in the log.

Tools like Interactive SQL and SQL Central want to provide you with column names, and all kinds of of other meta-data. Hence the "weird" queries. You wouldn't see this in your own applications unless you asked for it.

So if you see this query executed 11,000+ times, there must be something that you are doing 11,000+ times that would cause this. I'd look at the request level logging output to see what occurs between each of the getPrimaryKeys() calls.

[former_SQLA_member1694891]

I find that my procedure had a "SELECT ... FROM" instead of "SELECT ... INTO ...FROM" in a loop, but I was running it from interactive sql so it run the procedure normaly, it could be the reason of these weird query I saw in the profiler ?

[VolkerBarth]

Well, if your procedure does a regular SELECT (i.e. no INTO or not "SET ... = (SELECT...)", the result set will be returned to the caller, in your case to DBISQL. And that (as Jack has explained) will try to describe the result set in order to provide a fitting representation within its GUI (say, it has to know the result sets column names, data types and the like).

So, if your procedure does return such a result set within a loop, DBISQL will try to display as many result sets, and therefore will issue that many calls to get the according meta-data.

[jack_schueler]

This looks like the query that is generated for the ODBC SQLPrimaryKeys() function. Do you have any ODBC applications running against the database?

[Breck_Carter]

Please answer the questions in the first comment on your original question.

[Breck_Carter]

That query MAY have come from dbisql. You can see it and MANY MORE "strange queries" by starting dbsrv17 -zr ALL and then running this query in dbisql: SELECT * FROM dummy.

Here's what the request level logging output looks like (I'm sure scjview.exe does something similar):

Scroll down half-way to see your query "select cast(null as char(128))..."

Breck is correct. It could have come from dbisql since dbisql uses the JDBC driver which is built on ODBC and the JDBC driver makes use of SQLPrimaryKeys (getPrimaryKeys()) and other schema functions such as SQLTables (getTables(), getCatalogs(), getSchemas(), getTableTypes()), and many more.

But that would not yet explain several thousand calls of that ODBC catalog query, right?

It might, if a stored procedure called xp_cmdshell inside a loop to repeatedly run dbisql, instead of EXECUTE IMMEDIATE inside a loop... the difference in overhead might be significant 🙂
