Oracle sql update regexp replace

This function, introduced in Oracle 10g, will allow you to replace a sequence of characters in a string with another set of characters using regular expression pattern matching. It can be a combination of the following:. The function will then replace this first word with 'CheckYourMath'. It will replace the occurrences with a character. In this case, it will skip over the 2 and 5 numeric values and replace 10 with a character.

In this example, we are going to replace all two-digit values from the address field in the contacts table with the value 'TBD'. The next example that we will look at involves using the pattern. The pattern is used like an "OR" to specify more than one alternative. This example will return 'AndGrsGn' because it is searching for the first vowel a, e, i, o, or u in the string. This time, the 'A' in 'Anderson' will be found as a match. Notice also that we specified 0 as the 5th parameter so that all occurrences would be replaced.

If you omit this parameter, the period does not match the newline character. If you omit this parameter, Oracle treats the source string as a single line.

If you specify multiple contradictory values, Oracle uses the last value. For example, if you specify 'ic' , then Oracle uses case-sensitive matching. It can contain up to bytes.
