hello oll my table like on the up side. I have a price and I have many rules on the price column. I want to get all the column id value for my price value.

If priceopetaror is 0 then price1 is bigger then my price else if priceopetaror is 1 then price1 is smaller then my price else if ........

How I get all the row numbers for these rows.

Answer 1

If you are wanting help building an if statement in sql

SELECT if(priceopetaror = 0, 'Bigger', if(priceopetaror = 1, 'Smaller', '')) as 'Some Column Name' from dtvs_risk_analizine_girmeme_tanimi_t

at this point you have all rows and a string containing what you have specified as your desired value. You can now add a where statement to the end of your query.

where priceopetaror = 0 or priceopetaror = 1

This will ensure you only get rows that have a value of 0 or 1
