How i can execute a query in PostgreSQL with, case
insensitive and accent insensitive.


Ass.: Fabio Alves Francelino

RE: Case

PostgreSQL keywords, table names, and column names are case-insensitive by default, unless you put quote delimiters around them:

seLeCt "TableName"."ColumnName", "tablename"."columnname" FROM "TableName", "tablename" ordEr By "tablename"."columnname" aSc;

You could even have a table or column called "Select", if you always put it inside quotes, to differentiate it from SQL SELECT.

See http://www.postgresql.org/idocs/index.php?sql-syntax.html for more info.

RE: Case

You don't understand.

The case is in data into a table.

Select * from [Table] Where [collum] like 'a%'.

This query must return the records:
A...* return
a...* no return
Á...* no return

I found in help the operator ~~* that works.

Select * from [Table] Where [collum] ~~* 'a%'.
A...* return
a...* return
Á...* return

But i don't want replace the like operator.

I ask for a solution that works for all queries with like operator.

How a propertie that you set in Server PostGreSQL.

How in the instalation of SQL Server.

Any way thank you

RE: Case

For case-insensitive LIKE comparisons, just use the ILIKE operator. (see http://www.postgresql.org/idocs/index.php?functions-matching.html) I don't know if that would work with accented characters, though, so you might have to keep working with regular expressions.

Also, you can cast any string result to lower-case or upper-case, if you want (http://www.postgresql.org/idocs/index.php?functions-string.html):

Select * from [Table] Where lower([column]) like 'a%';
Select * from [Table] Where upper([column]) like 'A%';
