No. It is because Flt has REAL affinity, but 1.0 has no affinity. You
can use CAST to explicitly give it one:
Hi again,
CREATE TABLE test (A TEXT);
INSERT INTO test VALUES ('1');
SELECT * FROM test WHERE A=1; -- returns 1
SELECT * FROM test WHERE A=1.0; -- returns nothing because the RHS is
converted to '1.0'
This would not have been a problem if CAST(1.0 AS TEXT) produced '1' (like
FloatToStr does in

Not quite going to work either. I should have said the values are _nearly_
always integers, but
Hi Richard,
Thank you for the quick reply. I cannot change the type of the column. The
tables are user defined and need to be matched with other user defined
tables. The values are always integers but can be in any type of column.
So I have to detect integers in order to avoid the .0 How do
Hi All,
CREATE TABLE test (A TEXT);
INSERT INTO test VALUES ('1');
SELECT * FROM test WHERE A=1; // returns 1
SELECT * FROM test WHERE A=1.0; // returns nothing
How is the second comparison done?
I realize that you can have double values that are too large to convert to
int64, but as I

Because column A has type TEXT, the RHS of the = is converted to text
and a text
9 matches
