Question

PL/SQL create table procedure and single quotes

Asked by: Aliencenet

i have a query that drops a table using execute immediate and then i'm trying to create a table using execute immediate. Do i have to include execute immediate (' create table blah') into quotes?
i want to create table this way but it doesn't work:
execute immediate 'create table as (select id, decode(name,'KOST','MATCH', 'NONMATCH'')

is it because of other single quotes in decode function?

Apostrophe/single quote in a concatenated string

If you were to concatenate an apostrophe/single quote in a string, you need to enter 4 single quotes for Oracle to display a quote symbol. For example:

SELECT 'There' || '''' || 's Henry'
FROM dual;

'create table as (select id, decode(name,'|| '''' || KOST,'|| '''' || MATCH,'|| '''' || NONMATCH,'|| '''' || ')

if this is 10g you can define your own begin and end of string delimiters...

In this example,  everything between  q'[   and ]'  will be executed and you don't need to worry about escaping the quotes between those delimiters


begin
    execute immediate q'[create table xxx as (select 1 id, decode(name,'KOST','MATCH', 'NONMATCH') name from (select 'KOST' name from dual))]';
end;
