Insert MATLAB data into database table

Syntax

sqlwrite(conn,tablename,data)

sqlwrite(conn,tablename,data,Name,Value)

Description

example

sqlwrite(conn,tablename,data) inserts data from a MATLAB^® table into a database table. If the table exists in the database, this function appends the data in the MATLAB table as rows in the existing database table. If the table does not exist in the database, this function creates a table with the specified table name and then inserts the data as rows in the new table. This syntax is the equivalent of executing SQL statements that contain the CREATE TABLE and INSERT INTO ANSI SQL syntaxes.

example

sqlwrite(conn,tablename,data,Name,Value) uses additional options specified by one or more name-value pair arguments. For example, 'Catalog','toy_store' inserts data into a database table that is located in the database catalog named toy_store.

Append Data into Existing Table

Open Script

Use an ODBC connection to append product data from a MATLAB® table into an existing table in a Microsoft® SQL Server® database.

Create an ODBC database connection to a Microsoft SQL Server database with Windows® authentication. Specify a blank user name and password. The database contains the table productTable.

datasource = 'MS SQL Server Auth';conn = database(datasource,'','');

Check the database connection. If the Message property is empty, then the connection is successful.

Input Arguments

collapse all

`data` — Data to insert
table

Data to insert into a database table, specified as a table.

The valid data types in a MATLAB table are:

Numeric array
Cell array of numeric arrays
Cell array of character vectors
String array
Datetime array
Duration array
Logical array
Cell array of logical arrays

The numeric array can contain these data types:

int8
uint8
int16
uint16
int32
uint32
int64
uint64
single
double

For date and time data, supported formats are:

Date — 'yyyy-MM-dd'
Time — 'hh:mm:ss'
Timestamp — 'yyyy-MM-dd HH:mm:ss'

If the date and time data is specified in an invalid format, then the sqlwrite function automatically converts the data to a supported format.

If the cell array of character vectors or string array is specified in an invalid format, then the sqlwrite function enables the database driver to check the format. If the format is unexpected, then the database driver throws an error.

You can insert data in an existing database table or a new database table. The data types of variables in data vary depending on whether the database table exists. For valid data types, see Data Types for Existing Table and Data Types for New Table.

Note

The sqlwrite function supports only the table data type for the data input argument. To insert data stored in a structure, cell array, or numeric matrix, convert the data to a table by using the struct2table, cell2table, and array2table functions, respectively.

The sqlwrite function does not support the database preferences NullNumberWrite and NullStringWrite. To insert missing data, see Accepted Missing Data.

Example: table([10;20],{'M';'F'})

Data Types for Existing Table

The variable names of the MATLAB table must match the column names in the database table. The sqlwrite function is case-sensitive.

When you insert data into a database table, use the data types shown in the following table to ensure that the data has the correct data type. This table matches the valid data types of the MATLAB table variable to the data types of the database column. For example, when you insert data into a database column that has the BOOLEAN data type, ensure that the corresponding variable in the MATLAB table is a logical array or cell array of logical arrays.

Data Type of MATLAB Table Variable	Data Type of Existing Database Column
Numeric array or cell array of numeric arrays	`NUMERIC`
Cell array of character vectors String array Datetime array Duration array	`DATE`, `TIME`, or `DATETIME`
Logical array or cell array of logical arrays	`BIT` or `BOOLEAN`
Cell array of character vectors or string array	`CHAR` `VARCHAR` `TEXT` `NTEXT` Other text data type

Data Types for New Table

The specified table name for the new database table must be unique across all tables in the database.

The valid data types in a MATLAB table are:

Numeric array
Cell array of character vectors
String array
Datetime array
Duration array
Logical array

The sqlwrite function ignores any invalid variable types and inserts only the valid variables from MATLAB as columns in a new database table.

The sqlwrite function converts the data type of the variable into the default data type of the column in the database table. The following table matches the valid data types of the MATLAB table variable to the default data types of the database column.

Data Type of MATLAB Table Variable	Default Data Type of Database Column
Numeric array or cell array of numeric arrays	`NUMERIC`
Datetime array	`TIMESTAMP`
Duration array	`TIME`
Logical array	`NUMERIC`
String array	`VARCHAR` Note The size of this column equals the sum of the maximum length of a string in the string array and 100.
Cell array of character vectors	`VARCHAR` Note The size of this column equals the sum of the maximum length of a character vector in the cell array and 100.

To specify database-specific column data types instead of the defaults, use the 'ColumnType' name-value pair argument. For example, you can specify 'ColumnType',"bigint" to create a BIGINT column in the new database table.

Also, using the 'ColumnType' name-value pair argument, you can specify other data types that are not in the default list. For example, to insert images, specify 'ColumnType',"image".

Accepted Missing Data

The accepted missing data for inserting data into a database depends on the data type of the MATLAB table variable and the data type of the column in the database. The following table matches the data type of the MATLAB table variable to the data type of the database column and specifies the accepted missing data to use in each case.

Data Type of MATLAB Table Variable	Data Type of Database Column	Accepted Missing Data
`datetime` array	`Date`, `Time`, or `Timestamp`	`NaT`
`duration` array	`Time`	`NaN`
`double` or `single` array	`Numeric` `Double` `Float` `Decimal` `Real`	`NaN`
cell array of `double` or `single` arrays	`Numeric` `Double` `Float` `Decimal` `Real`	`NaN`, `[]`, or `''`
cell array of character vectors	`Date`, `Time`, or `Timestamp`	`'NaT'` or `''`
cell array of character vectors	`Char`, `Varchar`, or other text data type	`''`
string array	`Date`, `Time`, or `Timestamp`	`""`, `"NaT"`, or `missing`
string array	`Char`, `Varchar`, or other text data type	`missing`

Data Types: table

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: sqlwrite(conn,"tablename",data,'ColumnType',["numeric" "timestamp" "image"]) inserts data into a new database table named tablename by specifying data types for all columns in the new database table.

`Catalog` — Database catalog name
string scalar | character vector

Database catalog name, specified as a string scalar or character vector. A catalog serves as the container for the schemas in a database and contains related metadata information. A database can have multiple catalogs.

Example: Catalog = "toy_store"

Data Types: string | char

`Schema` — Database schema name
string scalar | character vector

Database schema name, specified as a string scalar or character vector. 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: string | char

`ColumnType` — Database column types
character vector | string scalar | cell array of character vectors | string array

Database column types, specified as a character vector, string scalar, cell array of character vectors, or string array. Use this name-value pair argument to define custom data types for the columns in a database table. Specify a column type for each column in the table.

Example: 'ColumnType',["numeric" "varchar(400)"]

Data Types: char | string | cell
