Automatic Type Determination For Database Programming

A non-transitory machine-readable medium storing a program executable by at least one processing unit of a device, the program comprising sets of instructions for:

• receiving a programming language statement comprising a variable, an expression to which the variable is set, and a request to determine a data type of the variable;
• processing the expression to deduce a data type of an expression;
• and
• assigning the data type of the expression as the data type of the variable, the data type of the variable for use when the programming language is compiled into machine executable code.

A system comprising:

• a set of processing units;
• and
• a non-transitory machine-readable medium storing instructions that when executed by at least one processing unit in the set of processing units cause the at least one processing unit to:
• receive a programming language statement comprising a variable, an expression to which the variable is set, and a request to determine a data type of the variable;
• process the expression to deduce a data type of the expression;
• and
• assign the data type of the expression as the data type of the variable, the data type of the variable for use when the programming language statement is compiled into machine executable code.
