I have a table that stores an XML data type. I'm trying to compare what is in the table against data that will be inserted.
How do I Query and compare a sql XML data type to a table XML column?
I converted the data column to a varchar and did a string compare.
In Oracle you could compare CLOB's by using dbms_lob.compare
I converted the data column to a varchar and did a string compare.

I have a XML data column in a SQL Server table. There are more than 5000 elements in the XML. I intended to make a table out of that XML formatted column.
As far as I'm aware, SQL has a limitation that a table can only have 1024 columns. How will I flatten the file so that it may be used for reporting?
I have dates in the format 01jan2020 (without a space or any separator) and need to convert this to a date type in SQL Server 2016 Management Studio.
The data was loaded from a .CSV file into a table (call it TestData, column is Fill_Date).
To join on a separate table to pull back data for another process, I need the TestData column Fill_Date to be in the correct format (MM-DD-YYYY) for my query to run correctly.
Fill_Date is currently in table TestData as datatype varchar(50).
I want to either see if it is possible to convert it with TestData table or directly insert the result into a 2nd table that is formatted.
Thanks (NEWB)
I ended up solving by converting the data while dropping into a temp table, deleting old value, and then inserting from that table back into the TestData table.
CONVERT(VARCHAR,CONVERT(date,[fill_date]),101) AS fill_date
I have a table with column name Logo which has a datatype nvarchar(max) but the content is already in Base64 format. I want to move data from this column to another column which has a data type varbinary(max). If i use convert function it converts the logo Byte to varbinary which was actually in byte. How can i do this.
Such as in the Logo column which has nvarchar(max) data type i have this -
'iVBORw0KGgoAAAANSUhEUgAAAFoAAABaCAYAAAA4qEECAAAACXBI......'
and i want to move exactly the same value to another column which has a data type varbinary(max).
Thanx in advance
I am reading between the lines here, but I think the OP is saying that have data in a varchar column that has values like '0x1A23494947D324B'. As a result something like SELECT CONVERT(varbinary,'0x1234'); doesn't return what the OP expects (0x307831323334).
You need to use a style code here, to let SQL Server know that the value is already in a varbinary format:
SELECT CONVERT(varbinary(MAX),'0x1234',1);
I am receiving an error
Conversion failed when converting the varchar value to data type int
while trying to insert data from one table into another. Both have the same table structure (table being inserted is an exact copy of the one used in the Select) and data types on the columns are the same.
INSERT INTO PS_PSOPRDEFN_BA
SELECT *
FROM PSOPRDEFN
Error:
Conversion failed when converting the varchar value '11000_600' to data type int.
The column this is inserting with this value is a varchar(30) in both tables, so I don't know why SQL is trying to convert it to int. Any ideas are appreciated.
When doing inserts, always include the columns:
INSERT INTO PS_PSOPRDEFN_BA ( . . . ) -- column list here
SELECT . . . -- column list here
FROM PSOPRDEFN;
You have a value which is a string which is being assigned to an integer column, and the value cannot be converted.
When doing an insert, the columns are aligned by order in the column list, not by name. So, merely having the same name doesn't mean that the code will work. The tables have to have exactly the same columns defined in the same order with compatible types for your code to work.
From the database there is a column which contains xml data in the format like:
<old_template_code> something </old_template_code><old_template_name> new
code</old_template_name><new_template_code>BEVA24M</new_template_code>
How can I extract the values from the xml and make a column for each of the different xml values? For example I would like to do something like:
select EXTRACTVALUE(table.column, table.column)
but the latter doesn't work for me.
