sqlfind

Find information about all table types in database

Syntax

data = sqlfind(conn,pattern)
data = sqlfind(conn,pattern,Name,Value)

Description

example

data = sqlfind(conn,pattern) returns information about all the Table Types in a database where the specified character pattern appears in the name of a table type. Executing this function is the equivalent of writing the SQL statement SELECT * FROM information_schema.tables.

example

data = sqlfind(conn,pattern,Name,Value) uses additional options specified by one or more name-value pair arguments. For example, 'Catalog','cat' finds all table types in the 'cat' catalog.

Input Arguments

collapse all

Database connection, specified as a connection object created with the database function.

Pattern, specified as a character vector or string scalar. The sqlfind function searches for this text in the names of the tables types in a database.

Example: "inventory"

Data Types: char | string

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: data = sqlfind(conn,pattern,'Catalog','toy_store','Schema','dbo') returns information about table types, stored in the specified catalog and schema, that match the name of the table type with the specified pattern.

Database catalog name, specified as the comma-separated pair consisting of 'Catalog' and a character vector or string scalar. A catalog serves as the container for the schemas in a database and contains related metadata information. A database can have numerous catalogs.

Example: 'Catalog','toy_store'

Data Types: char | string

Database schema name, specified as the comma-separated pair consisting of 'Schema' and a character vector or string scalar. A schema defines the database tables, views, relationships among tables, and other elements. A database catalog can have numerous schemas.

Example: 'Schema','dbo'

Data Types: char | string

Output Arguments

Table Types

Table types are a subset of database objects, which store or reference data.

The sqlfind function recognizes these table types in a database:

  • Table

  • View

  • System table

  • System view

  • Synonym

  • Global temporary table

  • Local temporary table
