The process of changing data type of a value into another data type is referred to as data type conversion and also almost all programing languages include some type of data converting functions or functionality. When we turn our perspective to SQL Server in order to discuss details of SQL data converting operations, at first we can separate data conversion process into two parts; implicit and explicit conversions. Explicit conversion is performed explicitly by a database programmer or administrator and at the same time this conversion process is made with help of any data conversion function. This function provides a means to convert one data type to another specified data type. The default value of this parameter is This value is more useful to date data type formats. In this example, we will convert a float data type to integer. In the following query, we will declare a variable that data type is float and then we will use the SQL CONVERT function in order to convert float value to integer so for that we will perform data converting operation. In this example, we will convert a float value to varchar value. This example is very similar to previous one but the only difference is that we will convert float value to varchar. In the following query, we will create a temporary table and we will insert converted value to this table and then we will analyze the data structure of this table. As you can see in the above image, the float data type was converted to varchar value and we did not set the length parameter so SQL Server applied the default value of the length parameter as The SQL Server money data type helps to store monetary values. We can define monetary values preceded by a currency symbol however SQL Server does not store the currency symbols or any data which is related to currency symbol.
