Re: Importing data from excel sheet
Hi, sam You can try to export table to file from Excel in CSV format. And then import data from this file to mysql. Something like this should help you: LOAD DATA INFILE 'yourtabledata.txt' INTO TABLE yourtable FIELDS TERMINATED BY ',' ENCLOSED BY '' LINES TERMINATED BY '\r\n'; sam rumaizan wrote: I have created table in mysql with 12 fields Field1Field2 Field3 Field4 ……… Field12 I have an excel sheet with 12 columns and 150 rows.

How can I do something like this in mySQL...
I have a query that looks something like this: SELECT (c_o_w_inst_rev - c_o_w_estcost)/c_o_w_inst_rev FROM tmpGovernmentSummaries The problem is that sometimes c_o_w_inst_rev is 0 and dividing by zero returns a NULL. If c_o_w_inst_rev == 0 how can I return 0 for the SELECT above instead of NULL? Can I test in the SELECT if c_o_w_inst_rev is 0 and return 0 and if not do the math? Insight would be greatly appreciated :-) -- John Kopanas [EMAIL PROTECTED] http://www.kopanas.com http://www.cusec.net http://www.soen.info -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Deleting pseudo-duplicates...
Vicente, A simple fast way is via an exclusion join: delete t1 from tbl t1 left join tbl t2 on t1.value=t2.value and t1.idt2.id where t2.id is not null; To understand how that works, notice that the query select t1.id from tbl t1 left join tbl t2 on t1.value=t2.value and t1.idt2.id where t2.id is null; returns row pairs matched on value values with minimum id values; therefore the query select t1.id from tbl t1 left join tbl t2 on t1.value=t2.value and t1.idt2.id where t2.id is not null; returns all remaining rows, and those are the ones deleted by the query given.

Re: How can I do something like this in mySQL...
Well, maybe you want to read up on isnull() and case (..) in the manual.
It's in there, somewhere.
mysql SELECT CASE 1 WHEN 1 THEN 'one'
- WHEN 2 THEN 'two' ELSE 'more' END;
- 'one'
mysql SELECT CASE WHEN 10 THEN 'true' ELSE 'false' END;
- 'true'
mysql SELECT CASE BINARY 'B'
- WHEN 'a' THEN 1 WHEN 'b' THEN 2 END;
- NULL
IF(expr1,expr2,expr3)
If expr1 is TRUE (expr1 0 and expr1 NULL) then IF() returns expr2;
otherwise it returns expr3. IF() returns a numeric or string value,
depending on the context in which it is used.
mysql SELECT IF(12,2,3);
- 3
mysql SELECT IF(12,'yes','no');
- 'yes'
mysql SELECT IF(STRCMP('test','test1'),'no','yes');
- 'no'
IFNULL(expr1,expr2)
If expr1 is not NULL, IFNULL() returns expr1; otherwise it returns expr2.
IFNULL() returns a numeric or string value, depending on the context in
which it is used.
mysql SELECT IFNULL(1,0);
- 1
mysql SELECT IFNULL(NULL,10);
- 10
mysql SELECT IFNULL(1/0,10);
- 10
mysql SELECT IFNULL(1/0,'yes');
- 'yes'
