I'm pretty new on Firebird.. trying to write a query that drops the table if exists through IBOConsole.
I have written the following sql statement,
EXECUTE block as
BEGIN
if (exists(
SELECT 1 FROM RDB$RELATIONS Where RDB$RELATION_NAME = 'ZZGTTUNIQUEID'))
then
execute statement 'DROP TABLE ZZGTTUNIQUEID';
END
but getting the following result..
ISC ERROR CODE:335544569
ISC ERROR MESSAGE:
Dynamic SQL Error
SQL error code = -104
Unexpected end of command - line 6, column 19
i'm not sure what might be wrong?
In IBOConsole I also experienced problems using the EXECUTE BLOCK statement, resulting in a 'Problem in BindingCursor' message and not executing the statement on the database. Use IBExpert's script executive or FlameRobin instead and it will work.

Attempting to perform operations with a random integer in SQL.
The following code works perfectly as intended when run as pure SQL, but triggers a syntax error when attempting to save it into a stored procedure.
SET #sample_count = (SELECT count(*)
FROM cinder_sample);
SELECT #sample_count;
SET #random_ID = (SELECT FLOOR(RAND()*#sample_count));
SELECT #random_ID;
Any ideas as to what could be going wrong?
The exact error triggered is:
"The following query has failed: "CREATE DEFINER=root#localhost PROCEDURE play_random_sp() NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER DELIMITER // SET #sample_count = (SELECT count() FROM cinder_sample)// SELECT #sample_count// SET #random_ID = (SELECT FLOOR(RAND()#sample_count))// SELECT #random_ID"
MySQL said: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '// SET #sample_count = (SELECT count(*) FROM cinder_sample)// SELECT' at line 1"
New to SQL and trying to run this code and I get the error "#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '#Qtable TABLE(Qid INT) END' at line 3". The code runs fine if I take out the DECLARE statement;
SET #query_id = (SELECT ID from ua820988_dev.users WHERE `email` = 'example#gmail.com');
CREATE PROCEDURE query_requests()
BEGIN
DECLARE #Qtable TABLE(Qid INT)
END;
SELECT * from ua820988_dev.requests WHERE `match` = #query_id;
SELECT * from ua820988_dev.requests_archive WHERE `match` = #query_id;
I'm hoping to eventually put the results from the 2nd and 3rd SELECT statements into the table, but this is the watered down version for now just trying to get the code to run. I'm running SQL 5.6 on MariaDB 10.2.
On IBMi (database is DB2 for i) in SQLRPGLE I have a program that builds a large SQL statement into a variable that I would like to run.
When I try to run it as a variable I receive a token error
Some background
Here is an example that works because it does not use a variable
Exec SQL
Create table MyLib/MyFile as(select * from XXLIB/XXFILE)
DATA INITIALLY DEFERRED REFRESH DEFERRED
maintained by user;
When I save this in a variable like #SQLStm and then try to execute as SQL
Exec SQL
:#SQLStm;
I get the error
Token : was not valid. Valid tokens: .
Also I am open to different approaches
https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_71/cl/runsqlstm.htm
Like RUNSQLSTM SRCFILE(MYLIB/MYFILE) SRCMBR(MYMBR)
Maybe there is a way to take a variable and save it to a source member?
Then use RUNSQLSTM over the source member
Showing some code:
Definition for the variable
d #SQLStm s A Len(6144) Varying(4)
Even when trying a portion of the SQL statement as a variable
#SQLStm = select * from XXLIB/XXFILE;
and then try:
Exec SQL
Create table MyLib/MyFile as( :#SQLStm)
DATA INITIALLY DEFERRED REFRESH DEFERRED
maintained by user;
I get the error
Token : was not valid. Valid tokens: .
I expect the SQLRPLE to compile
Instead of SQL precompile failed.
MSG ID SEV RECORD TEXT
SQL0104 30 236 Position 31 Token : was not valid. Valid tokens:
.
Message Summary
Total Info Warning Error Severe Terminal

This is static SQL
Exec SQL
Create table MyLib/MyFile as(select * from XXLIB/XXFILE)
DATA INITIALLY DEFERRED REFRESH DEFERRED
maintained by user;
What you want is dynamic SQL
wSqlStmt = 'Create table MyLib/MyFile as(select * from XXLIB/XXFILE)'
+ ' DATA INITIALLY DEFERRED REFRESH DEFERRED'
+ ' maintained by user';
exec SQL
execute immediate :wSqlStmt;
Note that some statements can't be execute immediate instead you have to prepare then execute them.
more information can be found in the Embedded SQL programming manual.
I am trying to use a simple IF ELSE query to test a feature with DB2 SQL. However when I attempt to execute it, I run into an error stating that I am not allowed to execute DDL statements.
What is throwing me off is that as far as I know, only database structure altering statements are considered DDL statements.
What gives?
Code:
IF 'True' = 'True' THEN
SELECT * FROM RM_TRANSACTION
FETCH FIRST 2 ROWS ONLY
FOR READ ONLY WITH UR
ELSE
SELECT * FROM RM_TRANSACTION
FETCH FIRST 4 ROWS ONLY
FOR READ ONLY WITH UR
END IF

The problem is that you can’t ‘select to nowhere’ in a compound statement in DB2. Db2 CLP can return you the result set of a single sql statement, but it doesn’t try to do the same for select statements in a compound statement.
If you want to print the result set from a select statement in a compound statement, you can, for example, declare a cursor, fetch it in a loop, and use dbms_output.put_line calls to print the values of variables.
Does any body know why the following SQL returns a syntax error (Incorrect syntax near 'IF') in SQL Server 2012?
DROP PROCEDURE IF EXISTS MyStoredProcedure;
I know I can use the following instead:
IF EXISTS(SELECT 1 FROM sys.procedures
WHERE Name = 'MyStoredProcedure')
But I wonder why the first one produces the error.
Thanks!
This works:
IF EXISTS(SELECT 1 FROM sys.procedures
WHERE Name = 'MyStoredProcedure')
print 'yes'
-- drop procedure mystoredprocedure
You must have something else in your query window that's throwing the error, or you're running things in the wrong order.
For what it's worth, this is my "go to" for dropping/building procedures before I CREATE PROCEDURE... all my saved proc scripts have this.
IF OBJECT_ID('dbo.uspSomeProcName') IS NOT NULL
BEGIN
DROP PROCEDURE dbo.uspSomeProcName
IF OBJECT_ID('dbo.uspSomeProcName') IS NOT NULL
PRINT '<<< FAILED DROPPING PROCEDURE dbo.uspSomeProcName>>>'
ELSE
PRINT '<<< DROPPED PROCEDURE dbo.uspSomeProcName>>>'
END
