function Update-DBOSchemaTable { <# .SYNOPSIS Adds extra columns the SchemaHistory table. .DESCRIPTION Upgrades an old version of the SchemaHistory table to a most recent version ensuring all the necessary columns are present. .PARAMETER SqlInstance Database server to use. Aliases: Server, SQLServer, DBServer, Instance .PARAMETER Database Name of the database to execute the scripts in. Optional - will use default database if not specified. .PARAMETER ConnectionTimeout Database server connection timeout in seconds. Only affects connection attempts. Does not affect execution timeout. If 0, will wait for connection until the end of times. Default: 30 .PARAMETER ExecutionTimeout Script execution timeout. The script will be aborted if the execution takes more than specified number of seconds. If 0, the script is allowed to run until the end of times. Default: 0 .PARAMETER Encrypt Enables connection encryption. .PARAMETER Credential PSCredential object with username and password to login to the database server. .PARAMETER UserName An alternative to -Credential - specify username explicitly .PARAMETER Password An alternative to -Credential - specify password explicitly .PARAMETER SchemaVersionTable A table that would be upgraded. Default: SchemaVersions .PARAMETER Silent Will supress all output from the command. .PARAMETER Variables Hashtable with variables that can be used inside the scripts and deployment parameters. Proper format of the variable tokens is #{MyVariableName}. Format can be changed using "Set-DBODefaultSetting -Name config.variabletoken" Can also be provided as a part of Configuration hashtable: -Configuration @{ Variables = @{ Var1 = ...; Var2 = ...}} Will augment and/or overwrite Variables defined inside the package. .PARAMETER OutputFile Log output into specified file. .PARAMETER Append Append output to the -OutputFile instead of overwriting it. .PARAMETER ConnectionString Custom connection string that will override other connection parameters. IMPORTANT: Will also ignore user/password/credential parameters, so make sure to include proper authentication credentials into the string. .PARAMETER Configuration A custom configuration that will be used during a deployment, overriding existing parameters inside the package. Can be a Hashtable, a DBOpsConfig object, or a path to a json file. .PARAMETER Schema Use a specific schema (if supported by RDBMS) .PARAMETER Type Defines the driver to use when connecting to the database server. Available options: SqlServer (default), Oracle, PostgreSQL, MySQL .PARAMETER ConnectionAttribute Additional connection string attributes that should be added to the existing connection string, provided as a hashtable. For example to enable SYSDBA permissions in Oracle, use the following: -ConnectionAttribute @{ 'DBA Privilege' = 'SYSDBA' } .PARAMETER Confirm Prompts to confirm certain actions .PARAMETER WhatIf Shows what would happen if the command would execute, but does not actually perform the command .EXAMPLE # Upgrades default SchemaVersion table. Upgrade-DBOSchemaTable -SqlInstance 'myserver\instance1' .EXAMPLE # Upgrades a custom SchemaVersion table: MySchemaHistory Upgrade-DBOSchemaTable -SqlInstance 'myserver\instance1' -SchemaVersionTable 'MySchemaHistory' .EXAMPLE # Upgrades a custom SchemaVersion table: MySchemaHistory.
