Thank you. The reason it is not working is because you are not writing the query right. bteq << eof select 1 from DBC.TablesV where databasename = 'YOUR_DB'; --and TableName = 'YOUR_TABLE'; --Could add and table here. Or we can simply say, SQL Server Not Exists operator will return the results exactly opposite to the result returned by the Subquery. This subquery gets a list of customers that were created prior to 60 days ago. a literal value. To sum it up there is no easy "IF EXISTS" alternative in Teradata and it is not really possible to temporarily disable errors in SAS either (other than the slightly dangerous temporary redirection of the SAS log to a file). This could help you to check if DB exist and/or table and if bteq exit with 1 not to proceed with loading. The NOT IN operator allows you to specify multiple values in a WHERE clause. Above query will return only those records from table1 where 'id' value is not present in table2 operation on a table that you do not have access to; Solution You are trying to run a DML / DDL operation on a table that exists on a different database. SELECT * FROM table1 WHERE NOT EXISTS ( SELECT 1 FROM table2 WHERE table1.id=table2.id); Explanation: In the above example, 'table1.id=table2.id' equality is setting correlation between subquery table and main query table. The NOT EXISTS in SQL Server will check the Subquery for rows existence, and if there are no rows then it will return TRUE, otherwise FALSE. Basically you are asking to insert values when there is no record in your 'sandbox.inv_room_type_inventory_snpsht' table. Thanks, that seems clear. But if the members in the expression list is more, then the performance of ‘EXISTS’ is better than ‘IN’.This is because, while using ‘IN’ if the set of constants consists of 70 or fewer members, the system uses hashing to retrieve the rows. .if activitycount = 0 then .quit 1 .quit 0 eof Would that be performance saavy compared to using it once ? Any help would be greatly appreciated. Next, the NOT EXISTS subquery runs. The parser complains about the final ON where you try to join offer_loj_do and offer_loj_od, but only offer_loj_do_final and offer_loj_od_final are within the current scope. Since the second subquery uses the NOT EXISTS statement, the main query does a match with the NOT EXISTS subquery against the customer database, and filters out records where they exist … WHERE NOT EXISTS ( sel '1' from TB3 3 where and 3.tb3='string') is how I think it should look . Problem here is I am calling TB3 a big FAT table twice. you are trying to run a SELECT / INSERT / UPDATE / DELETE etc. So, in other words, even if there is only one record exists in 'sandbox.inv_room_type_inventory_snpsht', it won't insert … For more information on IN/NOT IN, see “IN/NOT IN” on page 943. literal. This answer seems to be the only route: Code the "IF EXISTS" part manually. a predicate that tests the existence of the expression or list of expressions in the list of literals (Literals syntax) or the subquery (Subquery syntax) to produce a TRUE, FALSE, or UNKNOWN result. Very sad. [NOT] IN. I realized this field exists in the PAYMT database and not the RFS_RV database but I cannot figure out why I'm getting this message. https://www.wisdomjobs.com/e-university/teradata-tutorial-212/exists-6035.html A valid join condition would be. Hi,The performance of ‘EXISTS’ and ‘IN’ will be same for queries having fewer members in their expression list. Syntax: expression NOT IN (value1, value2, .... value_n); Example: ON offer_loj_do_final.sub_id1 = offer_loj_od_final.subs_id But this makes no sense, you join two Derived Tables with exactly the same Select.
