Maximum size is: Raw binary data of variable length up to 2 gigabytes. If you want to store the rowids of an index-organized table, then you can define a column of type UROWID for the table and retrieve the value of the ROWID pseudocolumn into that column. The REAL data type is a floating-point number with a binary precision of 63, or 18 decimal. Frequently, the error that occurs when converting a value from decimal to binary precision is undone when the value is converted back from binary to decimal precision. Both types of urowid are stored in the ROWID pseudocolumn (as are the physical rowids of heap-organized tables). If you try to insert a value that exceeds the specified length, then Oracle returns an error. LOB columns are subject to a number of rules and restrictions.

The default precision for this data type is 126 binary or 38 decimal. If the boolean value is true and n is not less than 4, then resulting value is true. Although the VARCHAR data type is currently synonymous with VARCHAR2, the VARCHAR data type is scheduled to be redefined as a separate data type used for variable-length character strings compared with different comparison semantics. Tag or not it is still what comes up in a search. The NUMBER data type stores zero as well as positive and negative fixed numbers with absolute values from 1.0 x 10-130 to but not including 1.0 x 10126. The Oracle-supplied types, along with cross-references to the documentation of their implementation and use, are described in the following sections: The Any types provide highly flexible modeling of procedure parameters and table columns where the actual type is not known. If data from a LONG column can be converted to a constrained data type (such as CHAR and VARCHAR2), then a LONG column can be referenced in a SQL statement within a trigger. Not applicable for DATE or TIMESTAMP. Use the VARCHAR2 data type instead. You can view a nested table as a single-column table or, if the nested table is an object type, as a multicolumn table, with a column for each attribute of the object type.
