select query using multiple like conditions - sql

Question

Below is an existing ms sql server 2008 report query.
SELECT
number, batchtype, customer, systemmonth, systemyear, entered, comment, totalpaid
FROM
payhistory LEFT OUTER JOIN agency ON
payhistory.SendingID = agency.agencyid
WHERE
payhistory.batchtype LIKE 'p%' AND
payhistory.entered >= '2011-08-01 00:00:00.00' AND
payhistory.entered < '2011-08-15 00:00:00.00' AND
payhistory.systemmonth = 8 AND
payhistory.systemyear = 2011 AND
payhistory.comment NOT LIKE 'Elit%'
Results will look like this:
number batchtype customer systemmonth systemyear entered comment totalpaid

What I am trying to do is modify the query that will exclude records where the customer is like 'FTS%' and 'EMC%' and batchtype = 'PC'. As you can see in the result set there are records where customer is like FTS% and batchtype = 'PA'. I would like to keep these records in the results. I would appreciate any ideas offered.

Answer 1

Your query contains a mix of upper and lower string comparison targets. As far as I'm aware, SQL Server is not by default case-sensitive; is it possible this is what is tripping your query up? Check collation per this answer.
EDIT: Based on your updated question, can you not just use an AND clause that uses a NOT on the front?
In other words, add a 'AND not (x)' clause, where 'x' is the conditions that define the records you want to exclude? You'd need to nest the customer test, because it's an OR.
e.g.:
... payhistory.comment NOT LIKE 'Elit%'
AND not ((customer like 'FTS%' or customer like 'EMC%') AND batchtype = 'PC')
As a side note, I believe that a LIKE clause may imply an inefficient table scan in some (but not all) cases, so if this query will be used in a performance-sensitive role you may want to check the query plan, and optimise the table to suit.

Answer 2

$sql="select * from builder_property where builder_pro_name LIKE '%%' OR builder_pro_name LIKE '%za%' AND status='Active'";
This will return all the builder property name in table that will ends name like plaza or complex.

Answer 3

It can be because your sever might be case sensitive. In that case, below query would work.
SELECT
table1.number, table1.btype, table1.cust, table1.comment, table2.ACode
FROM
table1 LEFT OUTER JOIN table2 ON table1.1ID = table2.2ID
WHERE
lower(table1.btype) LIKE 'p%' AND
lower(table1.comment) NOT LIKE 'yyy%' AND
lower(table1.cust) NOT LIKE 'abc%' AND
lower(table1.cust) NOT LIKE 'xyz%' AND
lower(table1.btype) <> 'pc'

Answer 4

Add this condition to the WHERE clause:
NOT((customer LIKE 'FTS%' OR customer LIKE 'EMC%') AND batchtype='PC')
Assuming your other results are OK and you just want to filter those out, the whole query would be
SELECT
number, batchtype, customer, systemmonth, systemyear, entered, comment, totalpaid
FROM
payhistory
LEFT OUTER JOIN agency ON
payhistory.SendingID = agency.agencyid
WHERE
payhistory.batchtype LIKE 'p%' AND
payhistory.entered >= '2011-08-01 00:00:00.00' AND
payhistory.entered < '2011-08-15 00:00:00.00' AND
payhistory.systemmonth = 8 AND
payhistory.systemyear = 2011 AND
payhistory.comment NOT LIKE 'Elit%' AND
NOT((payhistory.customer LIKE 'FTS%' OR payhistory.customer LIKE 'EMC%') AND payhistory.batchtype='PC')
Hope that works for you.

Answer 5

When building complex where clauses it is a good idea to use parenthesis to keep everything straight. Also when using multiple NOT LIKE statements you have to combine all of the NOT LIKE conditions together using ORs and wrap them inside of a separate AND condition like this...
WHERE
(payhistory.batchtype LIKE 'p%')
AND (payhistory.entered >= '2011-08-01 00:00:00.00')
AND (payhistory.entered < '2011-08-15 00:00:00.00')
AND (payhistory.systemmonth = 8 )
AND (payhistory.systemyear = 2011)
AND ( // BEGIN NOT LIKE CODE
(payhistory.comment NOT LIKE 'Elit%')
OR (
(payhistory.customer NOT LIKE 'EMC%') AND
(payhistory.batchtype = 'PC')
)
OR (
(payhistory.customer NOT LIKE 'FTS%') AND
(payhistory.batchtype = 'PC')
)
) //END NOT LIKE CODE
