Retrieves the byte position at which the specified byte array pattern begins within the BLOB value that this Blob object represents. The search for pattern begins at position start.
If the search is successful, position() returns the position at which the pattern appears; otherwise, position returns a value of -1.
position(byte pattern, long start)
- The byte array containing the pattern for which to search.
- The position at which to begin searching.
- The first position is 1.
|IF …||THEN position() throws an SQLException to …|
|there is an error accessing the BLOB value||indicate a failure while reading LOB data, setting the SQLException fields as follows:
|the value of the pattern argument is null
the value of the start argument is less than 1
|indicate an invalid argument, setting the SQLException fields as follows:
|the JVM cannot allocate enough memory for the method to search for the specified pattern||indicate that available JVM heap memory has run out, setting the SQLException fields as follows:
