Vba connection string text file

Again, the specific column width s are specified by the schema information. This governs how the column data types should be defined, based on the content: 1 : If the column contain different data types , treat it as a string. Otherwise, match the column to the best data type. That may cause an error in reading when we read a row that contains data that does not match the expected data type.

However, omitting it or setting it to NO seems to do nothing. The parameter should contain a fully qualified path. This will be discussed in more details in next article. This also can be described in the schema information. If you wish to use schema. It is not possible to put in other keywords and have it be parsed by the text file driver. For that reason, you will not be able to specify all the details about a text file from the connection string alone.

In theory, you can open or link a text file without any schema information but this will rarely work. In this situation, Access will simply assume the defaults for various options. If the text file conforms to all the current defaults then Access will succeed in reading the file. More importantly, absence of errors in opening or linking to the text file does not mean the data are represented meaningfully.

For example, specially formatted currency amounts might be interpreted as text rather than currency, and non-delimited text with commas within the text might be mis-parsed, adding unwanted columns. The defaults are determined in two possible places:. It is mandatory to have the correct encoding regardless of which methods you may use to access your text files.

As you will see in the next articles, both methods has a fairly large overlap in the capabilities. Therefore, you may find yourself having a choice of using either. The main difference boils down to whether you want the schema to be stored within your application or within a folder where text files are expected to be.

Use this property only when your query table is based on data from a text file with the QueryType property set to xlTextImport , and only if the value of the TextFileParseType property is xlDelimited.

If you import data by using the user interface, data from a web query or a text query is imported as a QueryTable object, while all other external data is imported as a ListObject object.

If you import data by using the object model, data from a web query or a text query must be imported as a QueryTable , while all other external data can be imported as either a ListObject or a QueryTable.
