I have a table which a column contain select queries . can somebody help me on how to execute it without using SP.
Eg:
Table1:
Col1
---
Select * from tabl2 where id=1;
Select * from tabl2 where id=3;
enter code here
You can use
EXECUTE sp_executesql #Query
to run your T-SQL
EDIT:
For Teradata :
CALL DBC.SysExecSQL(string_expression)

I know this isn't a specific bit of code or problem, but I am having trouble with a very similar issue to the person asking this (except theirs is for SQL Server): Combining INSERT INTO and WITH/CTE ...and I can't seem to find it out there on any SAP HANA help forums etc. so thought there may be an expert on here who can just give me a simple yes or no answer.
The SQL statement I am using contains multiple CTEs, but when I try to insert it tells me there is a Syntax error around the word INSERT. It is definitely laid out exactly the same as in the question I've linked above (spent hours checking), and I can post code samples if necessary but I simply want to know whether it is supported first! Thanks
Short answer:
No, CTEs are not supported for INSERT/UPDATE statements.
Longer answer:
SQLScript's INSERT/UPDATE commands are actually "borrowed" SQL commands as the documentation explains.
Checking the documentation for SQL INSERT we find that it supports a subquery as a source of values.
The subquery term is defined as part of the SQL SELECT statement. Checking the documentation for SELECT shows that <subquery> and <with_clause> are different, non-overlapping terms.
This means, that CTEs cannot be used in subqueries and therefore not be part of the subqueries used in INSERT/UPDATE commands.
You can, however, use SQLScript table variables in INSERT statements in your SQLScript blocks, which is very similar to CTEs:
DO BEGIN
te_a := SELECT 10, 'xyz' as VAL from dummy;
te_b := SELECT 20, 'abc' as VAL from dummy;
te_all := SELECT * from :te_a
UNION ALL SELECT * from :te_b;
INSERT INTO VALS
(SELECT * from :te_all);
END;
You can convert the CTE into a Sub-Select statement in many cases
You can use following
insert into city (city, countryid, citycode)
select
city, countryid, citycode
from (
-- CTE Expression as subselect
select * from city
-- end (CTE)
) cte
Instead of using following valid CTE command combined with INSERT (on SQL Server)
with cte as (
select * from city
)
insert into city (city, countryid, citycode)
select
city, countryid, citycode
from cte
SAP HANA includes this posibility, the order of the code is different than SQL Server:
INSERT INTO EXAMPLE (ID)
WITH cte1 AS (SELECT 1 AS ID FROM DUMMY)
SELECT ID FROM cte1;
Kindly help me writing below query in openquery.Thanks in advance
INSERT INTO Tablename
SELECT * FROM tablename1 WHERE insertionorderid IN (
SELECT orderid FROM temp_table2)
If you are trying to insert into SQL Server the syntax would be
INSERT INTO dbo.[YOURTABLE] SELECT * FROM [MATCHING_TABLE] WHERE CLAUSE
The caveat here is that the two tables must have identical schemas or you will have to explicitly define the columns. Also this will not work properly for tables with identity columns
I'm running Oracle 11G. Assume I have table named TEST_TABLE. I can see it when run :
SQL> SELECT TABLE_NAME FROM ALL_TABLES WHERE TABLE_NAME='TEST_TABLE';
TABLE_NAME
------------------------------
TEST_TABLE
But when I try to get table content I get an error:
SQL> SELECT * FROM table (TEST_TABLE);
SELECT * FROM table (TEST_TABLE)
*
ERROR at line 1:
ORA-00904: "TEST_TABLE": invalid identifier
Any help will be greatly appreciated !
SELECT * FROM table (TEST_TABLE);
That is the syntax for using a table function. Quite an advanced topic, not what you are looking for.
To access a table, simply do
SELECT * FROM TEST_TABLE;
i am trying to insert some rows and update some rows inside a pl/sql loop.
however all i get to see is the pl/sql procedure is successfully completed.
i do get to see dbmbs_ouput statements but not the output status of insert and/or update queries.
the serveroutput is set to on.
how do i get to see the status of insert and update rows(namely how many rows were inserted and updated)
In Oracle, the rowcount is not output automatically like it is in SQL Server.
You should do it explicitly:
BEGIN
INSERT
INTO mytable
SELECT …
FROM other_table;
DBMS_OUTPUT.put_line(SQL%ROWCOUNT);
END;
Does sqlite support the SELECT INTO statement?
Actually I am trying to save the data in table1 into table2 as a backup of my database before modifying the data.
When I try using the SELECT INTO statement:
SELECT * INTO equipments_backup FROM equipments;
I get a syntax error:
"Last Error Message:near "INTO":syntax
error".
Instead of
SELECT * INTO equipments_backup FROM equipments
try
CREATE TABLE equipments_backup AS SELECT * FROM equipments
sqlite does not support SELECT INTO.
You can probably use this form instead:
INSERT INTO equipments_backup SELECT * FROM equipments;
SQlite didn't have INSERT INTO syntax.
In 2019, I use TEMPORARY keyword to create temporary table and INSERT data to temp table:
CREATE TEMPORARY TABLE equipments_backup(field1 TEXT, field2 REAL)
INSERT INTO equipments_backup SELECT field1, field2 FROM equipments
