Control the import options by creating an SQLImportOptions object. Then, retrieve the default import options from a database table.

This example uses the patients.xls spreadsheet, which contains patient information. Also, the example uses a Microsoft® SQL Server® Version 11.00.2100 database and the Microsoft SQL Server Driver 11.00.5058.

Create a database connection to a Microsoft SQL Server database with Windows® authentication. Specify a blank user name and password.

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

Load patient information into the MATLAB® workspace.

patients = readtable('patients.xls');

Create the patients database table using the patient information.

tablename = 'patients';
sqlwrite(conn,tablename,patients)

Create an SQLImportOptions object using the patients database table and the databaseImportOptions function.

opts = databaseImportOptions(conn,tablename);

Retrieve and display the default import options for the patients database table.

varOpts = getoptions(opts)

varOpts = 
    1x10 SQLVariableImportOptions array with properties:

   Variable Options:
                    (1) |      (2) |      (3) |        (4) |      (5) |      (6) |      (7) |        (8) |         (9) |                       (10)  
       Name: 'LastName' | 'Gender' |    'Age' | 'Location' | 'Height' | 'Weight' | 'Smoker' | 'Systolic' | 'Diastolic' | 'SelfAssessedHealthStatus'
       Type:     'char' |   'char' | 'double' |     'char' | 'double' | 'double' | 'double' |   'double' |    'double' |                     'char'
  FillValue:         '' |       '' |    [NaN] |         '' |    [NaN] |    [NaN] |    [NaN] |      [NaN] |       [NaN] |                         ''

	To access sub-properties of each variable, use getoptions

To modify the variable import options, see the setoptions function.

Delete the patients database table using the execute function.

sqlquery = ['DROP TABLE ' tablename];
execute(conn,sqlquery)

Close the database connection.

close(conn)

Control the import options by creating an SQLImportOptions object. Then, retrieve the default import options for several columns from a database table. Specify the columns to retrieve by using the database column names.

This example uses the patients.xls spreadsheet, which contains the columns LastName, Age, and Location. Also, the example uses a Microsoft® SQL Server® Version 11.00.2100 database and the Microsoft SQL Server Driver 11.00.5058.

Create a database connection to a Microsoft SQL Server database with Windows® authentication. Specify a blank user name and password.

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

Load patient information into the MATLAB® workspace.

patients = readtable('patients.xls');

Create the patients database table using the patient information.

tablename = 'patients';
sqlwrite(conn,tablename,patients)

Create an SQLImportOptions object using the patients database table and the databaseImportOptions function.

opts = databaseImportOptions(conn,tablename);

Specify the names of the database columns in the patients database table.

varnames = {'LastName','Age','Location'};

Retrieve and display the default import options for the specified database columns.

varOpts = getoptions(opts,varnames)

varOpts = 
    1x3 SQLVariableImportOptions array with properties:

   Variable Options:
                    (1) |      (2) |        (3)  
       Name: 'LastName' |    'Age' | 'Location'
       Type:     'char' | 'double' |     'char'
  FillValue:         '' |    [NaN] |         ''

Delete the patients database table using the execute function.

sqlquery = ['DROP TABLE ' tablename];
execute(conn,sqlquery)

Close the database connection.

close(conn)

Control the import options by creating an SQLImportOptions object. Then, retrieve the default import options for several columns from a database table. Specify the columns to retrieve by using a numeric index.

This example uses the patients.xls spreadsheet, which contains the columns LastName, Gender, and Age. Also, the example uses a Microsoft® SQL Server® Version 11.00.2100 database and the Microsoft SQL Server Driver 11.00.5058.

Create a database connection to a Microsoft SQL Server database with Windows® authentication. Specify a blank user name and password.

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

Load patient information into the MATLAB® workspace.

patients = readtable('patients.xls');

Create the patients database table using the patient information.

tablename = 'patients';
sqlwrite(conn,tablename,patients)

Create an SQLImportOptions object using the patients database table and the databaseImportOptions function.

opts = databaseImportOptions(conn,tablename);

Specify the first three database columns by using a numeric index.

index = [1,2,3];

Retrieve and display the default import options for the specified database columns.

varOpts = getoptions(opts,index)

varOpts = 
    1x3 SQLVariableImportOptions array with properties:

   Variable Options:
                    (1) |      (2) |      (3)  
       Name: 'LastName' | 'Gender' |    'Age'
