note: the IsDate() will return 1 if the string value matches the current DATEFORMAT setting, which can be either YMD, DMY or MDY.<br />
you will get different results of IsDate() based on that setting.

so, in a filter, you can then use that function as if it were a legitimate datetime ( not neccessarily recommended for very large tables ) as in<br />
<br />
select * from mytable where isnull(dbo.uValidDate(myco<wbr />lumn),'190<wbr />00101') between getdate() &nbsp;- 90 and getdate()<br />
<br />
but then AngelIII's use of isdate probably answers your question...<br />

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Databases

Microsoft SQL Server 2005 is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning. It includes support for managing XML data and allows a database server to be exposed over web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests.

Microsoft SQL Server 2005

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
