I'm trying to execute the following code using isql:
IF (EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = N'SFPTB051_ABERTURARCLH'))
BEGIN
SELECT * FROM SFPTB051_ABERTURARCLH;
END
The way i'm doing:
isql -i sql_scripts/test.sql _input/mygdb.GDB -user SYSADM -pass masterkey
Output:
Statement failed, SQLSTATE = 42000
Dynamic SQL Error
-SQL error code = -104
-Token unknown - line 1, column 1
-IF
At line 1 in file sql_scripts/test.sql
Expected end of statement, encountered EOF
Any ideias?
Thanks!
UPDATE ---
I'm trying the following:
SET TERM # ;
EXECUTE BLOCK AS
BEGIN
SELECT * FROM SFPTB051_ABERTURARCLH
END#
SET TERM ; #
But it's returning:
Statement failed, SQLSTATE = 42000
Dynamic SQL Error
-SQL error code = -104
-Token unknown - line 4, column 1
-END
Usually, select statements within a block statement need to return their values. For example, you can return them into variables or return values, which are almost the same.
Furthermore, every statement within a block statement has to be terminated by a semi-colon (;).
Your block statement could look something like this:
SET TERM # ;
EXECUTE BLOCK AS
DECLARE VARIABLE FIELD1 TYPE OF COLUMN SFPTB051_ABERTURARCLH.FIELD1;
/* declare more variables as needed */
BEGIN
FOR
SELECT FIELD1
FROM SFPTB051_ABERTURARCLH
INTO :FIELD1
DO
BEGIN
/* do something with the variables values */
END
END#
SET TERM ; #

I have the following code in Maria DB ,
I want to use my function in a query to create a sequence that starts with the count(*) +1 of a my TABLE1
It gives me an error in the CREATE SEQUENCE query :
CREATE FUNCTION myFuntion() RETURNS INT
BEGIN
DECLARE lastID INT DEFAULT 1;
SELECT COUNT(*) INTO lastID FROM TABLE1;
RETURN lastID+1;
END;
CREATE SEQUENCE seq101 START WITH myFuntion() INCREMENT BY 1 ;
Error :
MySqlError { ERROR 1064 (42000): 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 'myFuntion() INCREMENT BY 1' }
I think the only way is to use a prepared statement and a variable, since user functions are not allowed in PREPARE FROM/EXECUTE IMMEDIATE.
SELECT count(*) + 1 INTO #lastid FROM yourtable
EXECUTE IMMEDIATE CONCAT("CREATE SEQUENCE seq101 START WITH ", #lastid," INCREMENT BY 1");
I tried to implement a page on APEX(19.2) , where the user has to make an input , which is the column name. This input shall restrict the select statement on the where clause and is the following:
select * FROM UEBERSICHT where
:P904_COLUMN = :P904_AUSDRUCK;
:P904_COLUMN and :P904_AUSDRUCK; are both APEX items, which is needed for the user input.
When I write the column name instead of :P904_COLUMN, I get an output, otherwise not.
But as the headline says, I want to implement a dynamic column.
I also tried it with PL/SQL , which returns a SQL - statement like the following:
declare
statement varchar2(4000);
begin
statement:= 'SELECT * FROM UEBERSICHT where
:P904_COLUMN = :P904_AUSDRUCK;';
return statement;
end;
Another approach was , to save the input on a variable first and write the variable name into the SQL - Statement:
declare
statement varchar2(4000);
spalte varchar2(50);
begin
if :P904_COLUMN = '"Gesellschaft"' then spalte := '"Gesellschaft"'; end if;
statement:= 'SELECT * FROM UEBERSICHT where
'||spalte||' = :P904_AUSDRUCK;';
return statement;
end;
Here i get this syntax error, which shouldn't appear normally: "ORA-20999: Parsing returned query results in "ORA-20999: Failed to parse SQL query! ORA-06550: line 5, column 6: ORA-00936: missing expression"."
How can I solve this problem ?
PS: Yes I am submitting all APEX items.
Update: The debug shows me that I get the Input, but the interactive Report doesn't give me any output though.
IF all the columns in :P904_COLUMN is of same data type you can use something like below where A and B are column names
select * FROM UEBERSICHT where
DECODE(:P904_COLUMN,'A',A,'B',B) = :P904_AUSDRUCK;
I am trying to build a ODI procedure, which will take schema name, db procedure name and parameters from a oracle database metadata table. The parameter field contains a name of a ODI global variable.The source command is like this
SELECT SCHEMA_NAME VAR_SCHEMA, PROCEDURE_NAME VAR_PROCEDURE, PARAMETER_NAME
VAR_PARAMETER FROM SCHEMA-NAME.TABLE_NAME
the output of the source command is like this:
VAR_SCHEMA_NAME VAR_TABLE_NAME VAR_PARAMETER
ABC PROC_LIST TO_DATE('#VAR_ETL_LOAD_DATE','DD/MM/RRRR')
Here, #VAR_ETL_LOAD_DATE is a global variable in ODI.
In the target command of the procedure, I want to use these information from source command to execute procedures listed in metadata table. I wrote a command like this:
DECLARE
VVC_SQL_STMT LONG;
BEGIN
VVC_SQL_STMT := 'BEGIN
#VAR_SCHEMA_NAME.#VAR_PROCEDURE_NAME(#VAR_PARAMETER);
END;';
INSERT INTO AK_TST2 VALUES(VVC_SQL_STMT,SYSDATE);
COMMIT;
EXECUTE IMMEDIATE (VVC_SQL_STMT);
END;
This code gives the following error in ODI:
ODI-1228: Task PROC_SP_HANDLER (Procedure) fails on the target ORACLE
connection OCDM_SYS.
Caused By: java.sql.SQLException: ORA-06550: line 8, column 61:
PLS-00103: Encountered the symbol "#" when expecting one of the following:
* & = - + ; < / > at in is mod remainder not rem
<an exponent (**)> <> or != or ~= >= <= <> and or like like2
like4 likec between || multiset member submultiset
What is the reasons for this and how can I execute stored procedures in ODI by reading procedure names and parameters from a metadata table?
If you select data from a table and use the result as a code for further execution, normally you cannot use ODI variables there. Because it too late for ODI to recognse that it is a variable and substitute it by a variable. This is the same for both global and project variables.
If you could print "#"+variable_name from ?- or %-substitution than it will work. But if #-substitution prints variable name or if variable appears as a final code after fetching values from Source it is too late. In this cases it remains as a plain text #VAR.
In your particular case you can do the following:
Declare all variables like #VAR_ETL_LOAD_DATE in a package. I mean all variables that could potentially appear in the metadata table. Bacause scenario should know all variables in advance.
Select and fetch records within ?-substitution using odiRef.getJDBCConnection('SRC'). Collect all results into a java-variable in the form of executable code.
E.g., source code could look like this:
select 1 from dual;
<?
import java.sql.*;
String crlf = System.getProperty("line.separator");
String result = "begin"+crlf+"null;"+crlf;
PreparedStatement stmt = odiRef.getJDBCConnection("SRC").prepareStatement("select schema||'.'||proc||'('||param||')' from metatable");
ResultSet rs = stmt.executeQuery();
while(rs.next()){
result += "insert into ak_tst2 values('"+rs.getString(1).replaceAll("'",'"'.toString())+"');"+crlf;
result += "commit;"+crlf;
result += rs.getString(1)+";"+crlf;
}
result += "end;";
rs.close();
stmt.close();
?>
Target code should be very simple
<?=result?>
At runtime target code will appear like this
begin
null;
insert into ak_tst2 values('qwe.asd("param_using_#var")');
commit;
qwe.asd('param_using_#var');
insert into ak_tst2 values('qwe2.asd2("param2_using_#var")');
commit;
qwe2.asd2('param2_using_#var');
insert into ak_tst2 values('qwe3.asd3("param3_using_#var")');
commit;
qwe3.asd3('param3_using_#var');
end;
And ODI variables will be successfully substituted by values.
I am having problems in following pl/sql anonymous. Here is the scaled down version of my pl/sql block..What is wrong with my code?
WHENEVER SQLERROR EXIT sql.sqlcode ROLLBACK
WHENEVER oserror EXIT FAILURE ROLLBACK

Here is the output I get

Based on the error you have reported I am guessing that somewhere in your PL/SQL block (which is not present in your question) you are referring to a table column named TIMESTAMP. Unfortunately this as a reserved word in Oracle as it is a column data type. I would recommend that you rename the column to something like DATE_CREATED and see if your code compiles.
I have a one line query:
DECLARE VARIABLE var_SecondsOfTime INTEGER;
But after running the query I am getting this message:
Engine Error (code = 335544569):
Dynamic SQL Error. SQL error code =
-104. Token unknown - line 1, column 9. VARIABLE.
SQL Error (code = -104): Invalid
token.
I've looked everywhere on the Internet and all examples showing the same declaration style which I am using.
What is wrong?
Firebird 2.5 supports execution of code blocks surrounded by a execute block statement, try this:
set term ^ ;
EXECUTE BLOCK
AS
DECLARE VARIABLE var_SecondsOfTime INTEGER;
BEGIN
SELECT 1 from RDB$DATABASE into var_SecondsOfTime ;
END
^
set term ; ^
I issued the select because I'm pretty sure it is not possible to execute an empty block, try this by yourself removing the select.
Edit
My original select was invalid for a block, I added the into clause to collect the result. I never used firebird maestro, but it now works perfectly on isql, as shown.
Try this:
set term ^ ;
EXECUTE BLOCK
AS
DECLARE VARIABLE var_SecondsOfTime INTEGER;
BEGIN
SELECT 1 from RDB$DATABASE into :var_SecondsOfTime ;
END^
set term ;^
The second set term needs the semi colon before the carat.
