Class DB2CodeGenerator
A specialized implementation of the CodeGenerator class for generating DB2-specific database schema and code representations. This class is responsible for transforming database schema information into DB2-compliant SQL code or other DB2-related output.

Constructors
DB2CodeGenerator()
Initializes a new instance of the CodeGenerator class that writes output to the console.
public DB2CodeGenerator()
DB2CodeGenerator(TextWriter)
Initializes a new instance of the CodeGenerator class with the specified TextWriter for output.
public DB2CodeGenerator(TextWriter output)
Parameters
outputTextWriterThe TextWriter to which the generated SQL will be written. Must not be null.
DB2CodeGenerator(string)
Initializes a new instance of the CodeGenerator class that writes output to a file at the specified path.
public DB2CodeGenerator(string path)
Parameters
pathstringThe file path where the generated SQL will be written. The file will be created if it does not exist, or appended to if it does. Must not be null or empty.
Properties
ProviderName
Gets the name of the database provider for which this code generator is designed to generate SQL scripts.
public override string ProviderName { get; }
Property Value
SupportsDbCreation
Gets a value indicating whether this code generator supports generating a CREATE DATABASE statement as part of the export process.
protected override bool SupportsDbCreation { get; }
Property Value
Methods
Format(object, ColumnType)
Formats a value for inclusion in a SQL statement, taking into account the value's type and the corresponding column type.
protected override string Format(object value, ColumnType columnType)
Parameters
valueobjectThe value to be formatted for inclusion in a SQL statement. This could be a default value for a column, a value being inserted into a table, or any other value that needs to be represented as a literal in the generated SQL. The method will determine how to format this value based on its type and the specified column type, ensuring that it is correctly represented in the SQL syntax for the target database provider.
columnTypeColumnTypeThe column type that corresponds to the value being formatted. This information is used to determine how to format the value, such as whether to quote it, how to format dates and times, how to represent binary data, etc., according to the conventions of the target database provider.
Returns
- string
A string representing the formatted value, ready to be included as a literal in a SQL statement, formatted according to the conventions of the target database provider.
GetTypeName(IDataItem)
Gets the SQL type name for the given data item, which could be a column or a user-defined data type.
protected override string GetTypeName(IDataItem item)
Parameters
itemIDataItemThe data item for which to determine the SQL type name. This could be a column or a user-defined data type. The method will use the properties of the data item, such as ColumnType, Size, Precision, and Scale, to determine the appropriate SQL type name, potentially using provider-specific type mappings and formatting rules.
Returns
- string
A string representing the SQL type name for the data item, formatted according to the conventions of the target database provider.
WriteIdentitySpecification(Column)
Writes the identity specification for the specified column.
protected override void WriteIdentitySpecification(Column column)
Parameters
columnColumnThe column for which the identity specification is being written.
