Hi

I've a table bins in which I've a column named "Date In"  which stores values of "Date" type. I've postgresql 8.3.5

Now when I execute query " select * from bins where "Date In" like '%'; " I get the folowing error :


SQL error:

ERROR:  operator does not exist: date ~~ unknown
LINE 1: select * from bins where "Date In" like '%';
                                           ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

In statement:
select * from bins where "Date In" like '%';
Please help...I'm stuck for like 3-4 hours now on this X_X

Hello

it means - there are not operator LIKE for datatype date. Why do you
do it? Try to look on date_part or extract functions.

Fast solution, bot not optimal, is cast date to text via function
to_char(date, 'mask')
