sqlite-vtfunc is implemented in Cython since pysqlitedoes not provide any hooks into the virtual table APIs. The virtual table mechanism of SQLite is an incredibly powerful tool, and is the basis for SQLite's full-text search engine, among other things. To support this level of complexity, the API is suitably dense. Table-valued functions, on the o...
In this section I'll walk through the creation of a table-valued function that returns all matching subgroups from a search via regular-expression. For example, suppose we want to filter out all the email addresses from a block of text. To get started, we need to define our function's parameters and it's result columns. For the regex search, we'll ...
It would be fantastic if SQLite provided an official C interface for creating minimal table-valued functions like these. I understand the reasons for not doing so, since there will always be folks like me who will write API wrappers, but having an official API would let library developers like @rogerbinns and @ghaeringcreate wrappers as part of the...

Table-valued Functions (TVF) Description. A table-valued function (TVF) is a function that returns a relation or a set of rows. There are two types of TVFs in Spark SQL: a TVF that can be specified in a FROM clause, e.g. range; a TVF that can be specified in SELECT/LATERAL VIEW clauses, e.g. explode. Supported Table-valued Functions TVFs that ...
Oct 30, 2024 · To create a table function, use the CREATE TABLE FUNCTION statement. A table function contains a query that produces a table. The function returns the query result. The following table function takes an INT64 parameter and uses this value inside a WHERE clause in a query over a public dataset called bigquery-public-data.usa_names.usa_1910_current:
