where-clause

I have a table that has millions of rows. Accidentally I wrote an update query over a table without where clause and clicked execute. It started executing. After two seconds I realized the query is wrong and I clicked ' Stop ' button in Sql Server Management Studio . The query execution was stopped, this all happened within 7 seconds. Now I am curious to know if there are any rows affected. If any which are they? How to find it? A single update statement will not update some rows. It's all rows or none This is the atomicity in the ACID properties which SQL server respects well. Atomicity

I tried googling for this issue but only find how to do it using two tables, as follows, INSERT INTO tbl_member SELECT Field1,Field2,Field3,... FROM temp_table WHERE NOT EXISTS(SELECT * FROM tbl_member WHERE (temp_table.Field1=tbl_member.Field1 and temp_table.Field2=tbl_member.Field2...etc.) ) This worked for one scenario,But now my interest is to upload data directly from the program itself without using two tables. What i want is to upload the data which is not in the table. The sql i had in my head was like the following, INSERT INTO tbl_member (SensorIdValue, DataTimeValue, DataInValue,

I am pretty new to VB.NET and am having a bit of trouble here with something I thought should be simple. Keeping it simple, let's say I have a Document table with "Name" that I want to search on (in reality there are several other tables, joins, etc. ..). I need to be able to build the query using a where clause based on string values passed in. Example - the user may pass in "ABC", "ABC DEF", "ABC DEF GHI". The final query would be (the syntax is not correct, I know): Select * from Documents Where Name Like %ABC% AND Name Like %DEF% AND Name like %GHI% So, I thought I could do something like

Found a couple of similar questions here on this, but couldn't figure out how to apply to my scenario. My function has a parameter called @IncludeBelow . Values are 0 or 1 (BIT). I have this query: SELECT p.* FROM Locations l INNER JOIN Posts p on l.LocationId = p.LocationId WHERE l.Condition1 = @Value1 AND l.SomeOtherCondition = @SomeOtherValue If @IncludeBelow is 0, i need the query to be this: SELECT p.* FROM Locations l INNER JOIN Posts p on l.LocationId = p.LocationId WHERE l.Condition1 = @Value1 AND l.SomeOtherCondition = @SomeOtherValue AND p.LocationType = @LocationType -- additional

I saw a query run in a log file on an application. and it contained a query like: SELECT ID FROM CUST_ATTR49 WHERE 1=0 what is the use of such a query that is bound to return nothing? A query like this can be used to ping the database. The clause: WHERE 1=0 Ensures that non data is sent back, so no CPU charge, no Network traffic or other resource consumption. A query like that can test for: server availability CUST_ATTR49 table existence ID column existence Keeping a connection alive Cause a trigger to fire without changing any rows manage many OR conditions in dynamic queries (e.g WHERE 1=0

I'm using the framework Laravel. I have 2 tables (Users and Members).
