I need to write a sqlplus script to create a table in oracle database, first to check if it is there, if not then create the table.
This is use execute immediate dynamic query, if it is only table that will easier I just use single quote after execute immediate to wrap the sql statement. but now I have more stuff like constraints and an index.
So I don't know where I should put the end single quote.
Below is the script:
PROMPT Starting Create_SCH_RETENTIONS_Table.sql;
DECLARE cnt NUMBER;
BEGIN
SELECT COUNT(*) INTO cnt
FROM user_tables
WHERE upper(table_name) = 'SCH_RETENTIONS';
IF cnt = 0 THEN
EXECUTE IMMEDIATE 'CREATE TABLE "DR"."SCH_RETENTIONS"
( "STUDENTID" NUMBER(10,0),
"STUDENT_NUMBER" FLOAT(126),
"RECOMMEND_SCHOOL_YEAR" NUMBER(4,0),
"RECOMMEND_SCHOOL" NUMBER(10,0),
"RECOMMEND_NAME" VARCHAR2(30 BYTE),
"NEXT_YEAR_GRADE" NUMBER(10,0),
"SPRING_GRADE" NUMBER(10,0),
"RETENTION_REASON" NUMBER(1,0),
"RETAIN_OR_PROMOTE" VARCHAR2(1 BYTE),
"CREATE_USER" VARCHAR2(30 BYTE),
"CREATE_DATE" DATE,
"NOTES" VARCHAR2(1000 BYTE)
) SEGMENT CREATION IMMEDIATE
