SnowSQL, procedure - error 904 when using variable in insert statement - sql

Question

I'm working on snowflake procedure in snowsql and want to use variable as value in insert statement - something like that:
execute immediate $$
declare
select_statement string;
begin
select_statement := '''Some text''';
INSERT INTO SOME_TABLE(MESSAGE) values (select_statement);
exception
when statement_error then
return object_construct('Error type', 'STATEMENT_ERROR',
'SQLCODE', sqlcode,
'SQLERRM', sqlerrm,
'SQLSTATE', sqlstate);
when other then
return object_construct('Error type', 'Other error',
'SQLCODE', sqlcode,
'SQLERRM', sqlerrm,
'SQLSTATE', sqlstate);
end;
$$
;
{
"Error type": "STATEMENT_ERROR",
"SQLCODE": 904,
"SQLERRM": "SQL compilation error: error line 1 at position 102\ninvalid identifier 'SELECT_STATEMENT'",
"SQLSTATE": "42000"
}
I was trying to use single quote as well
select_statement := 'Some text';
and also without declaring it and using let
let select_statement := 'Some text';
Each time getting the same error...

Answer 1

please try this.
create or replace table SOME_TABLE(MESSAGE varchar2 );
select * from SOME_TABLE;
execute immediate $$
declare
select_statement string;
begin
select_statement := '''Some text''';
INSERT INTO SOME_TABLE(MESSAGE) values (:select_statement);
exception
when statement_error then
return object_construct('Error type', 'STATEMENT_ERROR',
'SQLCODE', sqlcode,
'SQLERRM', sqlerrm,
'SQLSTATE', sqlstate);
when other then
return object_construct('Error type', 'Other error',
'SQLCODE', sqlcode,
'SQLERRM', sqlerrm,
'SQLSTATE', sqlstate);
end;
$$;

This just needs some minor adjustments to the syntax. To use execute immediate as a string, create the string with one or more bind variables. Use the "using" clause to bind them in the execute immediate.
create or replace table some_table(message string);
execute immediate $$
declare
rs resultset;
select_statement string;
ins string default 'INSERT INTO SOME_TABLE(MESSAGE) values (?)';
begin
select_statement := 'Some text';
rs := (execute immediate :ins using (select_statement));
return table(rs);
exception
when statement_error then
return object_construct('Error type', 'STATEMENT_ERROR',
'SQLCODE', sqlcode,
'SQLERRM', sqlerrm,
'SQLSTATE', sqlstate);
when other then
return object_construct('Error type', 'Other error',
'SQLCODE', sqlcode,
'SQLERRM', sqlerrm,
'SQLSTATE', sqlstate);
end;
$$
;
The return of the table is optional, but helps with the return for programmatic access or human readability.
