You are right, I also believe that there is a problem of functional overlap
in the implementation at that time:
- `get_table_schema`: Provides column structure, types, and comments
- `get_table_summary`: Provides table metadata and optional sample data
The sample output of `get_table_schema`:
```json
{
"success": true,
"timestamp": "2025-08-05 09:18:19",
"result": [
{
"column_name": "user_id",
"data_type": "bigint",
"is_nullable": false,
"default_value": null,
"comment": "",
"key": "true",
"extra": ""
},
{
"column_name": "name",
"data_type": "varchar(20)",
"is_nullable": false,
"default_value": null,
"comment": "",
"key": "false",
"extra": "NONE"
},
{
"column_name": "age",
"data_type": "int",
"is_nullable": false,
"default_value": null,
"comment": "",
"key": "false",
"extra": "NONE"
}
],
"message": "Operation successful",
"_execution_info": {
"tool_name": "get_table_schema",
"execution_time": 0.007,
"timestamp": "2025-08-05T09:18:19.837167"
}
}
```
the sample output of `get_table_summary`:
```json
{
"table_name": "test_streamload",
"comment": "",
"row_count": 10,
"create_time": "2025-08-04 09:29:58",
"engine": "Doris",
"column_count": 3,
"columns": [
{
"column_name": "user_id",
"data_type": "bigint",
"is_nullable": "NO",
"column_key": "DUP",
"column_comment": "用户 ID"
},
{
"column_name": "name",
"data_type": "varchar",
"is_nullable": "YES",
"column_key": "",
"column_comment": "用户姓名"
},
{
"column_name": "age",
"data_type": "int",
"is_nullable": "YES",
"column_key": "",
"column_comment": "用户年龄"
}
],
"sample_data": [
{
"user_id": 2,
"name": "Benjamin",
"age": 35
},
{
"user_id": 3,
"name": "Olivia",
"age": 28
}
],
"_execution_info": {
"tool_name": "get_table_summary",
"execution_time": 0.218,
"timestamp": "2025-08-05T09:29:47.557253"
}
}
```
Based on the above information and your suggestions, here I have a simple
solution:
## Tool Proposal: get_table_information
### Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| table_name | string | Yes | - | Name of the table to analyze |
| db_name | string | No | Current DB | Target database name |
| include_schema | boolean | No | true | Whether to include schema
information (columns, types, comments) |
| include_sample | boolean | No | false | Whether to include sample data
rows |
| sample_size | integer | No | 3 | Number of sample rows to return when
include_sample=true |
### Response Structure
```json
{
"basic_info": {
"table_name": "string",
"db_name": "string",
"row_count": "number",
"comment": "string"
},
"columns": [
{
"name": "string",
"type": "string",
"comment": "string",
"is_nullable": "boolean"
}
],
"sample_data": [
{
// sample rows
}
]
}
```
