Description

Prepares the parameters.

Prepare prepares the list of parameters as follows:

• If the data type of a parameter is ftUnknown, it changes to ADefaultDataType.
• If the parameter type of a parameter is ptUnknown, it changes to ADefaultParamType.
• If the size of a parameter is a negative value, it changes to 0.
• If the bind mode of the list of parameters is pbByName, but there are parameters that do not have a name, Prepare changes the bind mode to pbByNumber.
• If the bind mode is pbByNumber, but there are parameters that do not have a position, Prepare sets the value of their Position property to the position that they hold in the list of parameters.
