SQL Data Types. When you create column names for a table, each column must contain a data type. A data type specifies the type of data a column can store.

This page asks you to identify the different types of Oracle PL/SQL variables when programming PL/SQL.

In this example, the data type of the @model_year variable is SMALLINT. By default, when a variable is declared, its value is set to NULL. In SQL, numbers are defined as either exact or approximate. The exact numeric data types are SMALLINT, INTEGER, BIGINT, NUMERIC (p,s), and DECIMAL (p,s). Exact SQL numeric data type means that the value is stored as a literal representation of the number's value. The approximate numeric data types are FLOAT (p), REAL, and DOUBLE PRECISION. Although a First Name and a Book Title variables should use the varchar type, both variables would not have the same length of entries.

Although a First Name and a Book Title variables should use the varchar type, both variables would not have the same length of entries. As it happens, people hardly have a first name that is beyond 20 characters and many book titles go beyond 32 characters. In this case, both variables would use the same data type but different lengths.

Select COLUMN_NAME, DATA_TYPE, DATA_LENGTH, DATA_PRECISION, DATA_SCALE From cols Where table_name = 'Your_Table'; Varchar2 memory allocation. For a CHAR variable, PL/SQL allocates at compile time enough memory for the maximum size. For a VARCHAR2 variable, memory allocation depends on the variables maximum size: The type of a table variable in the body of a procedure or a table function is either derived from the SQL Query, or declared explicitly.

Supports both kind of tables SQL & Oracle , like in create table I had used a mix of sql and oracle data types. 2.Support for creating user defined types, currently

Assigning a system-supplied or user-defined data type and a length. For numeric variables, a precision and scale are also assigned.

SQL data types, SQLLEN values, and SQLTYPE values that the precompiler uses for host variables in COBOL programs. No exact equivalent. Use DECIMAL ( i + d, d) or NUMERIC ( i + d, d) No exact equivalent. Use DECIMAL ( i + d, d) or NUMERIC ( i + d, d) If a host variable includes an indicator variable, the SQLTYPE value is the base Since there are various kinds of information a database can deal with, SQL provides a set of data types. Boolean Variables. A Boolean value is a piece of information stated as being true or false, On or Off, Yes or No, 1 or 0.

This chapter explains scalar data types, which store values with no internal components. Data types define what type of data a column can contain. The following sections describe each PointBase data type in detail and discuss converting data types. Tables are provided at the end of the chapter to show the mappings between PointBase data types and industry standard and other common non-standard data types. 1970-01-01 · Data types in Standard SQL.

The sql_variant data type allows a table column or a variable to hold values of any data type with a maximum length of 8000 bytes plus 16 bytes that holds the data type information, but there are exceptions as noted below. This allows you to have flexibility in the type of data that is stored.

16. Is it possible to determine the type of a local variable at runtime in TSQL? For example, say I wanted to do something along these lines: IF ( @value IS INTEGER ) Or. IF ( TYPEOF (@value) = ) Does anyone know of any way to accomplish this?
