Alright, you fucking cocksuckers! Listen up!

So, we got this fucking request from server A, right?

$queryA = mysql_query("SELECT * FROM table");

And then, we also got another fucking request from server B!

$queryB = mysql_query("SELECT * FROM table");

Now, pay fucking attention! These two motherfucking tables are almost the fucking same, except for the fucking data. The data from server A is only partially equal to the fucking data from server B, at the fucking beginning.

Here's what the dumbass wants to do — the shithead wants to fetch the fucking data from these two tables and stick it into one damn mysql_fetch_array. Can you fucking believe that? The question is, is it even fucking possible?

Well, my dear friends, let me tell you something. This fucking challenge can be tackled with some fucking creativity! You can use a fucking UNION statement to combine the fucking results from both queries into one.

But hold your fucking horses! Since the fucking result sets have different structure, you need to ensure that both queries return the same fucking columns. And to fucking sort them by date, you can simply add an ORDER BY clause.

So, there you have it, you dumb shits! It is fucking possible to fetch the data from two motherfucking tables into one mysql_fetch_array, but you gotta be smart about it and fucking handle the differences in data and structure.

Now, go forth, you bunch of cunts, and get that shit done!


The issue lies within the problem statement itself. One possible solution is to utilize the FEDERATED engine, which allows you to read data from another server. However, be prepared for potential frustrations regarding speed.

Alternatively, you can implement master-master replication in MySQL. This means that each server will act as both a master and a slave. Quite an interesting concept, isn't it? In the event of any issues, all you need to do is transfer the IP address. The data will then be automatically synchronized between the servers.


If my understanding is correct, once the main server is restored, you have unique data on the backup server. As a result, there is a need to consolidate the results.

In this case, the challenge lies not in combining two requests, but rather in synchronizing the main server with the backup after its restoration. Once the synchronization is complete, you can exclusively work with the main server going forward.

It's crucial to ensure that the data on both servers are aligned and up-to-date to avoid any discrepancies or conflicts in the future. Proper synchronization protocols and procedures should be implemented to maintain a seamless transition between the two servers.


1. Absolutely not. We're not dealing with Microsoft SQL Server here and its SSIS. Forget about that option altogether. Alternatively, you can consider utilizing the federated die.

Now, let me add a touch of my own perspective. It's understandable to feel frustrated when certain tools or features from other database management systems are not available in MySQL. However, it's crucial to explore alternative approaches and leverage the available capabilities to achieve your goals.

2. Speaking of backups, replication, and other related matters (as mentioned in the comments), MySQL offers a built-in replication mechanism that is highly likely to meet your needs. This mechanism allows you to effectively replicate and synchronize data between servers, ensuring redundancy and fault-tolerance. With this feature at your disposal, you can confidently address your backup and replication requirements.


Let's consider a scenario where we have a request coming in from server type1:

$query_type1 = mysql_query("SELECT * FROM table");

Similarly, there is another request coming in from server type2:

$query_type2 = mysql_query("SELECT * FROM table");

Now, allow me to provide some additional thoughts on this topic. It's important to note that the queries are essentially the same, with the only difference being the server type they originate from. This distinction might indicate variations in the data or the intended use of the retrieved information.

In situations like this, it becomes crucial to handle and process the data from each server accordingly, ensuring proper segregation or consolidation based on the specific requirements of your application or system. Additionally, it's worth considering implementing error handling mechanisms to gracefully handle any potential issues that may arise during the execution of these queries.


In this scenario, we are dealing with requests from two different servers, each returning data from similar but not identical tables. To accomplish the task of combining the results into a single dataset, there are several important steps to consider.

First, it's essential to ensure that the columns selected in both queries are aligned. This means identifying the common fields and ensuring that their datatypes and names match between the two result sets. If there are discrepancies, it may be necessary to alias or transform the columns to achieve uniformity.

Once the queries have been crafted to return compatible results, a UNION statement can be used to merge the datasets. However, it's crucial to keep in mind that the UNION operator expects the result sets to have the same number of columns, so any discrepancies in the column count between the queries must be addressed.

Additionally, to sort the merged data by date as per the requirement, an ORDER BY clause can be applied to the combined result set, specifying the date column for sorting.

Furthermore, given that the data from each server may have its own unique identifiers or attributes, it's important to consider how to distinguish and handle these differences in the merged dataset to avoid confusion or data integrity issues.

While merging data from multiple sources introduces complexities, with careful attention to aligning the queries, ensuring column consistency, and handling any variations in the data, it is indeed possible to fetch and combine the data from the two tables into a single result set for further processing or presentation.
