Copy Image data type from one table to another

Hi,
I've a column col1 of image data type in table1. I would like to copy the data from col1 to another image column col2 in table2. Before moving the value, checking has to be done to specify which col1 data from table1 is needed and the destination has to be checked too.

Example: insert into col2
(select col1 from table1 where table1_id =5)
where table2_id =6

Hence bcp wouldn't work. Can anyone suggest me a way to do it. I tried using writetext but then, i've to get data from col1 in a variable, which is not possible. Any suggestions would be very helpful.

Thanks in advance.
Ramya.I found the way to do it. Here is the code:

declare @.ptrvalsource binary(16)

DECLARE @.ptrvaldest binary(16)

select @.ptrvalsource =textptr(col1) from table1 where table1_id = 5

SELECT @.ptrvaldest = TEXTPTR(col2) FROM table2 where table2_id=6

updateTEXT table2.col2 @.ptrvaldest 0 null table1.col1 @.ptrvalsource

Thanks,
Ramya.

converting varchar to int

Syntax error converting the varchar value '3.1.7.4.3.9.' to a column of data type int...

how to overcome this problem ..

Hello Raj,

What should '3.1.7.4.3.9.' be, ayou wanting to remove the .'s to have it be 317439? Try this:

=cInt(Replace(Fields!Field1.Value, ".", ""))

Jarret

|||when i run the query it throws the error... i have to handle the error in the data tab itself... can you help me how to find the exact field in which the irregular datatype is located ...is there any way to track down the issue...|||

It is clearly an SQL error which cannot be solved in SSRS using expressions.

I'm assuming that your dataset is formed by a stored procedure, not plain SQL text.

The error is because you are trying to put an invalid integer value into a table (temporary table or user table) column which is of INT datatype. If possible, get the SQL text of the stored procedure and check all insert/update statements and all the columns of INT datatype involved in it. Also check If there is an implicit conversion using CONVERT or CAST function.

|||can you tell me the problem is with varchar or datetime... because i didnt find any varchar like '3.1.7.4.3.9.'|||

Yes, it is definitely a varchar. You may have to look out for columns in the table that is being used as source to insert/update the value in the table which has a corresponding column of INT datatype.

|||thank you shyam .. i will check it out...

converting the varchar value to int

All,
I am running this statement and getting the error below. I am assuming
that the issue is the CLCCHRGE.CCOUNT data type is Varchar and needs to
be converted using a CONVERT clause or a CASE statement but I am not
sure I am on the right path here and if I am then I am not sure of the
syntax.
SELECT CLCHRGE.CCOUNT, CLCHRGE.CPTPRT, CLCHRGE.XCDATE,
CLMSTER.PLNAME, CLMSTER.PFNAME, procdesc, dignosis
FROM CLCHRGE INNER JOIN
CLMATER ON CLCHRGE.CCOUNT = CLMSTER.CCOUNT
WHERE (CLCHRGE.XACDATE BETWEEN '2005-01-01' AND '2005-1-31')
AND (CLCHRGE.CPTPINT = '90801') AND CLCHRGE.CCOUNT in (608685, 477078,
608201, 204739)
order by xacdate, plname desc
Server: Msg 245, Level 16, State 1, Line 1
Syntax error converting the varchar value 'C171913' to a column of data

CLCHRGE.CCOUNT in (608685, 477078,

to this

converting sql_variant column type to int

Hi,
I've got a table which has got a sql_variant column (sql server instance is 2000). the current data in that column are all numbers so can be converted to int.
I want to change the column type from sql_variant to int for that column. I have tried

alter table mytable alter column mycolumn int

and it complains
Disallowed implicit conversion from data type sql_variant to data type int, table 'mydatabase.dbo.mytable ', column 'mycolumn '. Use the CONVERT function to run this query.

I can do this task using EM but what that does is creating a new table temp table with int column type transferring data , dropping the original table and renaming the temp table to initial name.

therefore I need T-SQL command
Thanks

Really, I think I would suggest the same thing that you describe the EM doing -- drop the constraints on the original table, create the new table, copy in the data and then drop the old table. Can we get second and third opinions here?|||problem: this is template for a table in production server, which can not be dropped and also there are many constraints that points to this table. so using EM is not an option.

|||I would start by scripting out the table from the EM and massaging the generated script. Again, I'm not sure that you are going to be able to get out of creating a new version of the table and I would like additional opinions on this.|||

See if this helps.

create table dbo.t1 (

c1 sql_variant null

)

go

insert into dbo.t1 values(1)

go

alter table dbo.t1

add c2 int

go

update dbo.t1

set c2 = cast(c1 as int)

go

alter table dbo.t1

drop column c1

go

exec sp_rename 'dbo.t1.c2', 'c1', 'COLUMN'

go

select *

from dbo.t1

go

drop table dbo.t1

go

If there are indexes or constraints referencing column [c1], you have to drop them first and recreating them after renaming new column.

|||good solution, but column order is important for me. I think I can got to syscolumn table and change the column order there but this won't work on 2005|||

Kolf,

> but column order is important for me

Sorry about it, that is the beauty about relational dbs, the position of the column is not important at all. If that is the case, there is not other option than creating a new table, move all data, drop constraints refrencing the table, drop old table, recreate constraints and indexes. That is what" Enterprise Manager" or "Management Studio" does.

converting nvarchar to Minutes:Seconds in MS SQL?

I have a field in nvarchar type. It contains data like 0, :23, 1:57, ... all in minutes and seconds. Now, I need to convert it to MM:SS using query and get the Average of this column. How can I do it? I have tried Avg(Convert(nvarchar(20), [Calling Time], 108)) .. but I got error :The average aggregateoperation cannot take a nvarchar data type as an argument.

Help!!!! :(

You need to convert the minutes and seconds into some decimals which can be used in Avg function. Let's say you want to get Avg seconds, then you may try:

SELECT AvgSeconds= AVG(CASE WHEN CHARINDEX(':',[Calling Time])=0
THEN CONVERT(DECIMAL(4,2),[Calling Time])*60
WHEN CHARINDEX(':',[Calling Time])=1
THEN CONVERT(DECIMAL(4,2),RIGHT([Calling Time],LEN([Calling Time])-1))
ELSE CONVERT(DECIMAL(4,2),SUBSTRING([Calling Time],1,CHARINDEX(':',[Calling Time])-1))*60
+CONVERT(DECIMAL(4,2),SUBSTRING([Calling Time],CHARINDEX(':',[Calling Time])+1,LEN([Calling Time])))
END)
FROM test_CntTime

Converting numeric data type to text data type

Hi,

I would like to convert a dollar amount ($1,500) to represent Fifteen
hundred dollars and 00/100 cents only for SQL reporting purposes. Is
this possible and can I incorporate the statement into an existing
left outer join query.

Thanks in advance,

Gavin[posted and mailed, please reply in news]

If it is for reporting issues, it may be better to do this on client
level, but you could use a table to hold the various strings. I would
suggest that it will be simpler to implement, if you permit 1500 to be
rendered as "One thousand five hundred".

The table would look like this:

CREATE TABLE numberstrs (nr tinyint NOT NULL
CONSTRAINT ck_nr CHECK (nr BETWEEN 0 AND 99),
str varchar(23) NOT NULL,
CONSTRAINT pk_nr PRIMARY KEY (nr))
go
INSERT numberstrs (nr, str) VALUES (0, '')
INSERT numberstrs (nr, str) VALUES (1, 'one')
...
INSERT numberstrs (nr, str) VALUES (99, 'ninety-nine')

You would then use it as

SELECT CASE WHEN mil.str IS NOT NULL
THEN mil.str + ' millions and '
ELSE ''
END +
CASE WHEN hth.str IS NOT NULL
THEN mil.str + ' hundred '
ELSE ''
END +
CASE WHEN th.str IS NOT NULL
THEN th.str + ' thousand and '
ELSE ''
END +
CASE WHEN hun.str IS NOT NULL
THEN hun.str + ' hundred '
ELSE ''
END +
one.str + ' dollars ' +
ltrim(str((a.amt * 100) % 100)) + '/100 cents'
FROM tbl a
JOIN numberstrs one ON a.amt % 100 = nr
LEFT JOIN numberstrs hun ON (convert(int, a.amt) / 100) % 10 = nr
LEFT JOIN numberstrs th ON (convert(int, a.amt) / 1000) % 100 = nr
LEFT JOIN numberstrs hth ON (convert(int, a.amt) / 100000) % 10 = nr
LEFT JOIN numberstrs mil ON (convert(int, a.amt) / 1000000) % 100 = nr

This is something I made up, and I have not tested it. I don't think
the result will be that excellent for all numbers. For instance 101
would not come out pretty if you want it as "One hundred and one".
For even values like "One million" you need to add some logic.

Notice that there is a upper limit of 100 millions as I have written the
query. You would also have to arrange for the first letter in the
resulting string to be uppercase.

You mention how would incorporate into an existing query, but since I
don't see that query and don't where you want the value, I'm not taking
a stab at that.

COnverting Numeric data type (Oracle) to Date Data type using SSIS

We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.

I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.

On Error, If I fail the component, then the error is :

There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

Regards

RH

If you are using a query to go against Oracle, you'll likely want to cast that as a varchar and then work with it in SSIS. Not sure that YYYYMMDD will cast to DT_DATE. You'll likely have to substring pieces of that to get it into a date. There are plenty of examples here on this forum for doing that. Just search for "YYYYMMDD."|||

Thanks for the reply. I used SQL on the OLEDB Source and added a TO_DATE expression in the SQL and use that column as input to my destination column.

This worked fine.
