select statement to find a column which contains the word



I am trying to find out how to select a row of data from a table, where a column contains a keyword (from a querystring)

How to select all columns except one column from a table ?



I can't figure out how to do this and hope you guys can give me a hint....

I want to select all columns from a table except one column:

For example,

A table has 20 columns : {1,2,3.....20}

To select all of columns in a table, i could use

is there a way to achieve this in a short form of Select?

BDC Column with Ability to Select Multiple Values


Use Case:

We are creating a storage location for technical product articles. These will be SharePoint publishing pages. Each page will have metadata assigned to it to make it searchable by properties. The possible values for one of the columns (Part Number) could potentially be sourced by our ERP system. I'd like to do this to eliminate the possibility of free-text entry errors, but there are probably over 10,000 parts so a drop-down list isn't feasible.


Ideal Situation:

The end user enters the part number and clicks a button to verify it against a BDC entry from our ERP system. If they weren't sure on the part number they needed, they could do a lookup from that metadata entry screen. They'd need to have the option to add multiple part numbers as one technical product article could reference multiple part numbers.



Is BDC an option for all of this or am I looking at a custom metadata solution? I thought I heard along the way that BDC only supported one value choice, but I couldn't find a verification for that in the forums.



Use BDC data in list as multi-select column

I have a document library that uses values from another system for its metadata.  Right now, we copy the values from the primary system into SharePoint so users can choose them.  I want to find a way to use the BDC connection that I have set up to automatically pull those values.  The problem is that the current metadata is set to multi-select.  So, I have a file that is in the library and it can be used for multiple clients - clients is a column in my library and users can select many entries.  When I set up a column to pull BDC data, it only allows single entry.  Does anyone have any ideas?

DataGridView>Edit Columns> Column Read Only property is unwilling to change

Hello, I am facing the following mystery: When changing the read only property of a column to false and reopening the "edit columns" window, it mysteriously turns back to true. Even when closing the designer and changing it in the designer code, the resulting execution does not allow edit, as well as when re-opening the designer you see true again.             this.numberDataGridViewTextBoxColumn1.DataPropertyName = "Number";             this.numberDataGridViewTextBoxColumn1.HeaderText = "Number";             this.numberDataGridViewTextBoxColumn1.Name = "numberDataGridViewTextBoxColumn1";             this.numberDataGridViewTextBoxColumn1.ReadOnly = true;//False is required We thought it might be related to data binding. rebinding the grid did not help as well. The is no other place in the code where it changes. Please advice, Thanks

SELECT statement to return NULL by matching data from another table.

Hi,I am fairly new at SQL and I have been struggling for days now trying to find an answer to my problem and i have come to the point where i have run out of ideas and about to give up. I'm hoping someone can put me in the correct path. The problem I have 3 table Table 1 Department" has the following columns: REF, NAME Table 2  "Department_Collection" has the following columns: REF, DEPARTMENT_REF, MANAGER_REF, STORE_REF, ACTIVE Table 3 Store" has the following columns: REF, NAME, STORE_ID  What i am trying to do is to take all the rows in the Department table and get a matching row (DEPARTMENT.NAME, DEPARTMENT_COLLECTION.REF) from the Department_Collection table, if it does not match any then still display DEPARTMENT.NAME but mark DEPARTMENT_COLLECTION.REF as null. I have tried the following select statement but it seem to remove all null values when supplied with a 'storename' SELECT DEPARTMENT.NAME, DEPARTMENT_COLLECTION.REF FROM DEPARTMENT_COLLECTION right outer join DEPARTMENT on DEPARTMENT_COLLECTION.DEPARTMENT_REF = DEPARTMENT.REF left outer join STORE on DEPARTMENT_COLLECTION.STORE_REF = STORE.REF where STORE.NAME = 'storename' order by DEPARTMENT.NAME   Any help will be greatly appreciated.
