Hi there. Currently got a problem with performing the following task:
Perform fulltext search on all tables that have created fulltext indexes in specific schema. Result should look like this:
<TABLE_NAME1> <ID_FROM_TABLE>
<TABLE_NAME1> <ID_FROM_TABLE>
<TABLE_NAME2> <ID_FROM_TABLE>
<TABLE_NAME2> <ID_FROM_TABLE>
At the moment all tables have the same ID column UOI_ID.
What I've tried so far is the following:
PROCEDURE "tuser"."dam.test.db.procedures::textSearch" ( in keyword NVARCHAR(300), out search_results "tuser"."dam.test.db::tuser.procedures.tt_search_results" )
LANGUAGE SQLSCRIPT
SQL SECURITY INVOKER
DEFAULT SCHEMA "tuser"
AS
BEGIN
/*****************************
Write your procedure logic
*****************************/
DECLARE counter Integer := 1;
DECLARE row_count Integer;
DECLARE table_name NVARCHAR(300);
DECLARE schema_name NVARCHAR(300) := 'tuser';
indexed_tables = SELECT row_number() OVER (ORDER BY "TABLE_NAME") AS ROW_NUMBER, "TABLE_NAME"
FROM (
SELECT DISTINCT "TABLE_NAME"
FROM "SYS"."FULLTEXT_INDEXES"
WHERE "SCHEMA_NAME" = :schema_name
);
SELECT COUNT(*) INTO row_count FROM :indexed_tables;
WHILE counter < row_count + 1 DO
SELECT '"tuser"."'||"TABLE_NAME"||'"' INTO table_name FROM :indexed_tables WHERE "ROW_NUMBER" = :counter;
temporary_results = SELECT :table_name AS TABLE_NAME, "OUI_ID" AS ID
FROM :table_name
WHERE contains(*, :keyword, fuzzy(0.5));
search_results = CE_UNION_ALL(:search_results, :temporary_results);
counter := counter + 1;
END WHILE;
END;
At this point it's impossible to perform the:
... FROM :table_name ...
The error is:
Could not create catalog object: scalar type is not allowed
Tried doing it with CE functions.
temporary_table = CE_COLUMN_TABLE(table_name);
The error is:
Dependent object not found: SqlScript; tuser.TABLE_NAME
So the question is: How to dynamically put table name into "FROM ..." statement?
).
