Cfquery update set

ID equals the current row then display all data in a text field and display a new update button if not then just output plain text To achieve the above, I do a major rewrite of my table, so it now looks like below:. I do this by adding some code into the top of index. From attribute, and if it equals DoEdit it then does the update, displays a short confirmation to the user, and outputs the data. After my BODY tag I insert some additional, that checks to see if DoUpdate has been run, and if so, it then displays a short note to our dear user:.

From parameter equals DoEdit. To make things easier, you might want to order the GetData query by either the Author, Title or Articleno rows. Suggestions for future work, could among many things include, how to update multiple rows, or how to create a preview page before the data is updated. For other drivers, check driver documentation.

If date of original query is after this date, CFML uses cached query data. To use cached data, current query must use same SQL statement, data source, query name, user name, password. When specifying a date value as a string, you must enclose it in quotation marks. If original query date falls within the time span, cached query data is used. CreateTimeSpan defines a period from the present, back. Takes effect only if query caching is enabled in the Administrator.

To use cached data, the current query must use the same SQL statement, data source, query name, user name, and password. Yes: If debugging is enabled, but the Administrator Database Activity option is not enabled, displays SQL submitted to datasource and number of records returned by query. This example does not use ColdFusion formatting functions.

As a result, start dates look like and salaries do not have dollar signs or commas. The user can replace the information in any field using any valid input format for the data. The Contract field requires special treatment because a check box appears and sets its value. The cfif structure puts a check mark in the check box if the Contract field value is Yes, and leaves the box empty otherwise.

The cfupdate tag is the easiest way to handle simple updates from a front-end form. The cfupdate tag has an almost identical syntax to the cfinsert tag. To use the cfupdate tag, include the primary key fields in your form submittal. The cfupdate tag automatically detects the primary key fields in the table that you are updating and looks for them in the submitted form fields. ColdFusion uses the primary key fields to select the record to update therefore, you cannot update the primary key value itself.

It then uses the remaining form fields that you submit to update the corresponding fields in the record. The following table describes the query variables, which are sometimes called query properties :.

In your CFML code, use these variables as if they are columns in a database table. Use the result attribute to specify the name of the structure that ColdFusion populates with these variables. You then use that structure name to refer to the query variables as the following example shows:.

Save the file and view it in your web browser:The number of employees now appears below the list of employees. If necessary, refresh your browser and scroll to see the RecordCount output. You now display the number of records retrieved in the query. The following table describes the code and its function:.
