A table-valued function that splits a string into rows of substrings, based on a specified separator character. To change the compatibility level of a database, refer to View or Change the Compatibility Level of a Database. Returns a single-column table whose rows are the substrings. The name of the column is value. Returns nvarchar if any of the input arguments are either nvarchar or nchar. Otherwise returns varchar. The length of the return type is the same as the length of the string argument.

The name of the output column is value. The output rows might be in any order. The order is not guaranteed to match the order of the substrings in the input string. Empty zero-length substrings are present when the input string contains two or more consecutive occurrences of the delimiter character.

Empty substrings are treated the same as are plain substrings. The order of the output may vary as the order is not guaranteed to match the order of the substrings in the input string. Users must create a report that shows the number of products per each tag, ordered by number of products, and to filter only the tags with more than two products.

Developers must create a query that finds articles by a list of IDs. They can use following query:. Or an anti-pattern can be achieved by using the LIKE operator.

This page.On this blog there are two articles about this technique, one is about splitting up a single string into multiple rows and the other is about multiple strings into multiple rows.

SQL Server - Pass multiple values to singe parameter in stored procedure pass integers

Links to both articles are included at the bottom of this article. It seems like there is a need for functionality like that frequently. And just to add to those two articles on the subject, here is a third one combining the first two articles. To split this string up, you will need both techniques from the other articles.

Let's start with a variable containing the input string. The first step is to split the string up using the first method, split up the string using the comma as a delimiter.

Using these rows as the input in the next phase, use the technique described in the second article. You can see this on lines 6, 10, and Each value per line is not completely delimited by the forward slashes, the trailing one is missing.

Just to concatenate one to each line would be to easy, what if there is a trailing slash?

The RTRIM removes the trailing slash and concatenates one at the end, making sure that the string is split up at the right place. Part One Part Two. Nice combination of your methods, Alex :- An alternative if you can have multiple valid delimiters and they are all "equal" could be to translate all delimiters into the same for example comma.

Hi Alex, Thanks for this article. If you want to keep the special meaning of the delimiters, there is an alternative using "collection unnesting". Love it! Pages Blog Events - Past and Present. Links Part One Part Two. Alex Nuijten May 7, at PM. Stew Ashton May 8, at AM.

Tom, I'm not sure why you are concatenating ',' and in some cases ',' to :x? I'll keep testing but at the moment it works without them Regards Jim. Database Version: 8. Thanks a bunch What is the character limit on string that is being searched Looked in docs. Tom, Thanks for your help!

Will the above approach give me the best performance for aboutrows? Is there a way to identify the 45 positions once, in a before-insert trigger and substr each element in an after-insert trigger for faster performance? Are any other mehods available? Tom, The process to separate the Tab-delimited string needs to be executed from a stored-procedure. Sorry, I did not fully understand the solution.Typically, in SQL Server data tables and views, values such as a person's name or their address is stored in either a concatenated string or as individual columns for each part of the whole value.

This data could be stored in a single column with all the data, in two columns separating the person's name from their address or in multiple columns with a column for each piece of the total value of the data.

With this, DBA's are inevitably always having to concatenate or parse the values to suit our customer's needs. To build on our sample from above, I have an address column that has the full address street number and name, city and state separated by commas in a concatenated column. I want to break that data into three columns street, city and state respectively.

For this tip, let's create a test database and test table for the parsing example. In this scenario, we have a street name and number, followed by the city, then the state.

The following code creates a table in the new test database with only two columns - an id column and an address column. Populate the table with some generic data. Notice that the address is one string value in one column. Your results should return, as expected, two columns - the id column and the address column. Notice the address column is returned as a single string value in image 1. Breaking down the data into individual columns. The next step will be to parse out the three individual parts of the address that are separated by a comma.

Since we didn't call the id column in the SELECT statement above, the results only returned the address string divided into three columns, each column returning a portion of the address for the respective column as shown in image 2. Here in the real world, DBA's are often faced with more complex tables or views and not just a simple two column table as in the above sample. Although the sample above is a great primer for dissecting how to parse a string value, the following section demonstrates a more complex situation.

Again, create a sample table in our test database to work with. Here, we create a slightly more complex table with some additional columns.

Each time you start parsing a new column, you must start your count over.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I know this has been answered to some degree with PHP and MYSQL, but I was wondering if someone could teach me the simplest approach to splitting a string comma delimited into multiple rows in Oracle 10g preferably and 11g.

I've seen a few potential solutions around stack, however they only accounted for a single column being the comma delimited string. Any help would be greatly appreciated.

FROM without a join creates a cross join between your dataset and the multiset. The problem with this type of approach is that often the optimizer won't know the cardinality of the table function and it will have to make a guess. This could be potentialy harmful to your execution plans, so this solution can be extended to provide execution statistics for the optimizer. Even though the collection has only 3 values, the optimizer estimated rows for it default value. This may seem irrelevant at first, but it may be enough for the optimizer to decide for a sub-optimal plan.

As you can see the cardinality on the plan above is not the guessed value anymore. It's still not correct because we are passing a column instead of a string literal to the function.

Some tweaking to the function code would be necessary to give a closer estimate in this particular case, but I think the overall concept is pretty much explained here. Here's an Oracle 10g solution, adopted from Art's solution. I'd like to add another method. This one uses recursive querys, something I haven't seen in the other answers. It is supported by Oracle since 11gR2. It is quite flexible with the splitting character.

In Oracle 11g and later, you can use a recursive sub-query and simple string functions which may be faster than regular expressions and correlated hierarchical sub-queries :. Learn more.
