I would start by converting it to using joins instead of "classical joining": select t1. ID inner join Table3 t3 on t3. ID where t3. 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. In the following query, we will convert the money data type to varchar and we will also use style parameter of the SQL convert function. With the help of the style parameter, we can determine comma delimiters and length of the right decimal digit.
