Actually, your expectation is not wrong. But the effect can only be seen if there are millions of records. For lesser number of rows, it will reflect the same time.

Simple really, the update happened so quickly they are all the same time. Also be warned, SQL Server is only accurate (from memory) to a third of a millisecond.

That's a good information to have. Thanks.

Actually, DATETIME in SQL Server is only accurate to about 3 milliseconds. Which is not very accurate at all, in computing terms. There is a new datatype called DATETIME2 in the latest version of SQL Server which is accurate down to nanoseconds. Hundreds of highly trained database experts worked for weeks to come up with that name for the new datatype.

Converting rows into columns (PIVOT for string values)

I knew 3 and milliseconds came into, just couldn't remember where. I knew about datetime2 in 2008, but didn't realise so much time had been spent deciding on a name Big Grin | :-D

I have a small problem. I need to convert some rows into columns. Look at the following information.

Original Table:
Ind Sub String
0 1 22
0 2 21
0 3 5.6
0 4 John Rogers
1 1 12
1 2 76
1 3 99.3
1 4 Sarah Peters

Converted to:
Ind val1 val2 val3 val4
0 22 21 5.6 John Rogers
1 12 76 99.3 Sarah Peters

This is similar to a pivot, except that I am not count, averaging, counting, or any other agregating methods. Is there a simple query that will convert this or is this going to be a cursor issue?

Use Max(stringvalue) for your aggregate function (you are after all aggregating 1 value), you can see an example here[^]

Problem in joining 2 tables

Hi
I have 2 tables Table1 and Table2 as below

Table1 Table2
col1 col2 col1 col21 col31 col22 col32
1 xx 1 A 0 AA null
2 yy 1 B 0 BB null
3 zz 1 C 0 CC null
1 0 X null XX
1 0 Y null YY

now on joining 2 tables, i want the output as below

Table1.Col1 Table1.col2 Table2.col21 Table2.col31 Table2.col22 Table2.col32
1 xx A X AA XX
1 XX B Y BB YY
1 XX C null CC null

Am not sure whether join is to be used or what? Is there any way i can get the output like this. Table2 will have many other rows takking the col1 of Table1 as primary key.

Regards
Naina

I can't understand your question,where are separated data of Table1 and Table2?

The first table Table1 has a primary key and the foreign key is the column in the second table Table2

Now table 2 has the data like this

foreignkey col1 col2 col3 col4
1 naina 1 null null
1 karri 2 null null
1 xxxxx 3 null null
1 null null aaaa 1
1 null null bbbb 2

now i need the output to be like this

primarykey col1 col2 col3 col4
1 naina 1 aaaa 1
1 karri 2 bbbb 2

1 xxxxx 3 null null

it means that the first columns with null data should be replaced with the last columns with data for that particular primary key value

What you posted as a table is not aligned well. A Join can be done this way

Table1

ID    Name         ID_Number
==============================
1     Vuyiswa      810945212121
2     nainakarri   817454212121

Table2

ID    Name         ID_Number       Date_Added
=============================================
1     Vuyiswa      810945212121    2009-09-09
2     nainakarri   867454212121    2009-09-10
2     James        847454212121    2009-09-11
2     Daniel       837454212121    2009-09-12

Now to run a Join for this two tables you do something like this

SELECT * FROM TABLE1 T1
INNER JOIN  TABLE2 T2
ON T1.ID_NUMBER = T2.ID_NUMBER

as you can see i have used a "*" that means you have to select what ever columns you want.

Hope this Helps

Converted sql Query to Oracle

If table2 has a primary key of col1 of table1 what is that column called in table2, is it col21? If so, then this should do it:

select Table1.Col1, Table1.col2, Table2.col21, Table2.col31, Table2.col22, Table2.col32
from Table1 inner join Table2 on Table1.Col1 = Table2.Col21

You should really read up on joins though, this[^] explains them nicely.
