Re: InstantDB: Don't remember SQL...


Yes I did mean that...

Except none of these work as expected.

My string column is of type Text (without length), would this make a 
difference?? I wouldn't have believed so.

Here's a little test case performed within commsql (which, btw, 
should be marked a public class one, day...).

CREATE TABLE Names (i INTEGER, t TEXT)
INSERT INTO Names VALUES (0, Gueulu)
INSERT INTO Names VALUES (1, Grueulu)
INSERT INTO Names VALUES (2, Grulu)
SELECT * FROM Names
SELECT * FROM Names WHERE t LIKE "*eu*"
SELECT * FROM Names WHERE POSITION(Names.t, "eu") >0


which produces the following complete dump:

create table Names (i INTEGER, t TEXT)
java-thread-7 create table Names (i INTEGER, t TEXT)
Enter SQL string, or . to exit
INSERT INTO Names VALUES (0, Gueulu)

java-thread-7 INSERT INTO Names VALUES (0, Gueulu)
Enter SQL string, or . to exit
INSERT INTO Names VALUES (1, Grueulu)

java-thread-7 INSERT INTO Names VALUES (1, Grueulu)
Enter SQL string, or . to exit
INSERT INTO Names VALUES (2, Grulu)

java-thread-7 INSERT INTO Names VALUES (2, Grulu)
Enter SQL string, or . to exit
SELECT * FROM Names

java-thread-7 SELECT * FROM Names
3 rows returned
last  row: 2,Grulu
first row: 0,Gueulu
full results:
i,t
Row 1: 0,Gueulu
Row 2: 1,Grueulu
Row 3: 2,Grulu
Enter SQL string, or . to exit
SELECT * FROM Names WHERE t LIKE "*eu*"

java-thread-7 SELECT * FROM Names WHERE t LIKE "*eu*"
0 rows returned
last  row: java.sql.SQLException: Row number 0 is out of range
	at jdbc.idbResultsSet.setCurRow(idbResultsSet.java:122)
	at commsql.dispResultSet(Compiled Code)
	at commsql.main(Compiled Code)
	at org.jxe.tools.java.Java.main(Compiled Code)
	at org.jxe.kernel.Tool$ToolThread.run(Tool.java:215)
Enter SQL string, or . to exit



Gee I'm feeling beginner...
