I love concise videos that don't make me increase playback speed. Keep it up.

BTW You may run into an issue with the variable named "value" since it is a reserved keyword in SQL. This is causing the SQL parser to expect an identifier instead of the keyword!

I am glad this video exists. Very well done. Thank you.

[skydandelion]

Do more videos about Spring and Kotlin. This is a Great content over here. Thanx!

tuve un conflicto creeando la db, luego de leer un rato el error se debia a que H2 tenia a value como palabra reservada, lo modifique y listo

Why are you using System.out.println()? In kotlin, you can just use println()

Where are the SQL things being done and why is mine inserting random characters into it?

"select td1_0.id, td1_0.account_identifier, td1_0.date, td1_0.description, td1_0.[*]value from transactiondbmodel td1_0"; expected "identifier";

O sotaque a gente reconhece na hora heuheueh

Hello Juno,
Thanks for this tutorial

Could you help me? I got an error:
Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'transferRepository'

[hassanchop]

Great video! Why add extra boiler plate code by separating the DB models from the standard models? Couldn't you just make the top level models Spring Entities as well?

[chirayujoshi]

We are not good developers, we directly write code in production without any test cases

[Numerus-rt]

Can you please add tha arabic Translation to Video

[lecomar]

The quality of the information is good and concise
A lot of this is unfortunately too fast. When you create classes etc. and give names slowely clicking would be better. Its a bit exhausting too watch the video like that.

These random videos with too loud sound are terrible and not funny. You better increase your mic volume and speak more understandable.
