Description.  This type represents a condition based on the comparison of a column value with some arbitrary value—that is, a bound condition. A value of this type is used as the first argument to NdbScanFilter::cmp().

Enumeration values.  Possible values are shown, along with descriptions, in the following table:

When used in comparisons with COND_EQ, COND_NE, COND_LT, COND_LE, COND_GT, or COND_GE, fixed-length character and binary column values must be prefixed with the column size, and must be padded to length. This is not necessary for such values when used in COND_LIKE, COND_NOTLIKE, COL_AND_MASK_EQ_MASK, COL_AND_MASK_NE_MASK, COL_AND_MASK_EQ_ZERO, or COL_AND_MASK_NE_ZERO comparisons.

String comparisons.  Strings compared using COND_LIKE and COND_NOTLIKE can use the pattern metacharacters % and _. See Section 2.3.25.2.3, “NdbScanFilter::cmp()”, for more information.

BIT comparisons.  The BIT comparison operators COL_AND_MASK_EQ_MASK, COL_AND_MASK_NE_MASK, COL_AND_MASK_EQ_ZERO, and COL_AND_MASK_NE_ZERO were added in MySQL Cluster NDB 6.3.20. Corresponding methods are also available for NdbInterpretedCode and NdbOperation beginning with MySQL Cluster NDB 6.3.20; for more information about these methods, see Section 2.3.21.1.8, “NdbInterpretedCode Bitwise Comparison Operations”.

Description.  This type is used to describe logical (grouping) operators, and is used with the begin() method. (See Section 2.3.25.2.2, “NdbScanFilter::begin()”.)
